From its humble beginnings as a museum, showcasing dried and varnished morbid specimens—human relics of the Civil War, the institute became a leader in pathology. Later, it became a center of instruction for radiology residents seeking to understand the pathologic findings that underlay the radiologic appearance of disease. Images were gathered by the AFIP and the American Registry of Pathology (ARP) and have been used in research and education in radiology and other fields (ophthalmology, otalaryngology, dermatology, obstetrics and gynecology, and surgery). Despite the contributions of the AFI...

Radiologic imaging may not be required in patients with IBS without potentially concerning symptoms but should be considered where such symptoms exist, and choice of imaging study should be influenced by predominant symptoms. Definitive recommendations must await further research. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5631519 Thu, 26 Jan 2012 05:00:00 +0100 5631519 http://www.medworm.com/index.php?rid=5631518&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F262%2F2%2F475%3Frss%3D1 Conclusion: Extrinsic warming (to 37°C) does not appear to affect adverse event rates for intravenous injections of iopamidol 300 of less than 6 mL/sec but is associated with a significant reduction in extravasation and overall adverse event rates for the more viscous iopamidol 370. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5631518 Thu, 26 Jan 2012 05:00:00 +0100 5631518 http://www.medworm.com/index.php?rid=5631517&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F262%2F2%2F468%3Frss%3D1 Conclusion: Implementation of evidence-based CDS in the ED was associated with a significant decrease in use, and increase in yield, of CT pulmonary angiography for the evaluation of acute PE. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5631517 Thu, 26 Jan 2012 05:00:00 +0100 5631517 http://www.medworm.com/index.php?rid=5631516&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F262%2F2%2F460%3Frss%3D1 Conclusion: mCAC is a better predictor of CVE and all-cause mortality than FEV1 and emphysema extent and may contribute to the identification of high-risk individuals in a lung cancer screening setting. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110364/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5631516 Thu, 26 Jan 2012 05:00:00 +0100 5631516 http://www.medworm.com/index.php?rid=5631515&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F262%2F2%2F450%3Frss%3D1 Conclusion: Enhancement patterns and parameters of contrast-enhanced US may be useful in the noninvasive prediction of prognostic factors of breast cancers. © RSNA, 2012 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110789/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5631515 Thu, 26 Jan 2012 05:00:00 +0100 5631515 http://www.medworm.com/index.php?rid=5631514&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F262%2F2%2F435%3Frss%3D1 Conclusion: Adding SW elastographic features to BI-RADS feature analysis improved specificity of breast US mass assessment without loss of sensitivity. © RSNA, 2012 Clinical trial registration no.

Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained acceptance as a standalone imaging modality that can provide further information beyond the capabilities of traditional modalities such as echocardiography and angiography. Black-blood fast spin-echo MR images allow morphologic assessment of the heart with high spatial resolution, while T2-weighted MR images can depict acute myocardial edema. Contrast material–enhanced images can depict and be used to quantify myocardial edema, infil...

The purpose of this review is to describe the normal appearances of the prostatic region after different kinds of treatment for prostate cancer and to discuss how these appearances differ from those of recurrent and residual disease. Several MR imaging techniques used in evaluating patients with prostate cancer are described, including conventional MR imaging sequences (mainly T1- and T2-weighted sequences), MR spectroscopic imaging, diffusion-weighted imaging, and dynamic contr...

Because left-sided PTBD is the only independent risk factor associated with hepatic arterial injury, right-sided PTBD is preferable unless technical difficulty or secondary intervention necessitates left-sided PTBD. Moreover, transcatheter arterial embolization is a safe and effective method for treating hepatic arterial injury following PTBD. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424633 Thu, 17 Nov 2011 05:00:00 +0100 5424633 http://www.medworm.com/index.php?rid=5424632&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F960%3Frss%3D1 Conclusion: Splenic elasticity determined with RTE is the most closely associated parameter for evaluating HVPG and is useful as a clinical marker of portal hypertension and a predictive marker of gastroesophageal varices. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424632 Thu, 17 Nov 2011 05:00:00 +0100 5424632 http://www.medworm.com/index.php?rid=5424631&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F950%3Frss%3D1 Conclusion: Quantitative CT measurements of emphysema but not airway dimensions were only weakly associated with lung cancer, demonstrating no potential practical value for clinical risk stratification. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110542/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424631 Thu, 17 Nov 2011 05:00:00 +0100 5424631 http://www.medworm.com/index.php?rid=5424630&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F937%3Frss%3D1 Conclusion: Use of BS imaging together with a standard radiograph can improve radiologists’ accuracy for detection of small lung cancers on chest radiographs. Further improvements can be achieved by use of DES radiography but with the requirement for special equipment and a potential small increase in radiation dose. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424630 Thu, 17 Nov 2011 05:00:00 +0100 5424630 http://www.medworm.com/index.php?rid=5424629&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F930%3Frss%3D1 Conclusion: Maps of changes in OEF generated from SW phase images revealed changes in OEF corresponding to anticipated changes in CBF induced by various conditions; SW phase imaging might, in the future, be applied to evaluate cerebrovascular and other cerebral disorders in which changes in oxygen metabolism are important for planning therapeutic strategies. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424629 Thu, 17 Nov 2011 05:00:00 +0100 5424629 http://www.medworm.com/index.php?rid=5424628&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F923%3Frss%3D1 Conclusion: Flow velocity can be measured from row-to-row multidetector CT projectional data obtained during a single gantry revolution as a bolus of contrast material flows through a vascular phantom. With further development, this novel technique could potentially provide physiologic information to complement the anatomic CT angiographic findings of vascular disease. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424628 Thu, 17 Nov 2011 05:00:00 +0100 5424628 http://www.medworm.com/index.php?rid=5424627&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F916%3Frss%3D1 Conclusion: PCC is a safe and useful technique for early exclusion when biliary atresia cannot be ruled out after traditional screening tests; in addition, it may be useful for preoperative type determination of biliary atresia. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424627 Thu, 17 Nov 2011 05:00:00 +0100 5424627 http://www.medworm.com/index.php?rid=5424626&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F907%3Frss%3D1 Conclusion: Decreasing the dose of 99mTc-MAG3 from 7.4 to 2.2 MBq/kg did not compromise image quality. With noise reduction, the dose can be reduced to 1.5 MBq/kg without subjective loss in image quality. The quantitative evaluation of renal function was not substantially altered, even with a theoretical dose as low as 0.74 MBq/kg. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424626 Thu, 17 Nov 2011 05:00:00 +0100 5424626 http://www.medworm.com/index.php?rid=5424625&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F899%3Frss%3D1 Conclusion: Because of its high incidence in preterm infants around TEA, its absence after a postmenstrual age of 50 weeks, and its association with normal neurologic outcome at a corrected age of 2 years, DEHSI should not be considered part of the spectrum of WM injury, but rather a prematurity-related developmental phenomenon. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424625 Thu, 17 Nov 2011 05:00:00 +0100 5424625 http://www.medworm.com/index.php?rid=5424624&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F891%3Frss%3D1 Conclusion: Compared with control subjects, patients with RRMS had an increase in FA of NAGM that strongly correlated with cortical lesion volume and clinical disability. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424624 Thu, 17 Nov 2011 05:00:00 +0100 5424624 http://www.medworm.com/index.php?rid=5424623&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F882%3Frss%3D1 Conclusion: Histogram analysis of ADC maps based on entire tumor volume can be a useful tool for grading gliomas.

FDG PET could be used as a noninvasive surrogate marker for tumor growth and viability in this tumor model. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110361/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424616 Thu, 17 Nov 2011 05:00:00 +0100 5424616 http://www.medworm.com/index.php?rid=5424615&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F805%3Frss%3D1 Conclusion: This study showed that contrast-enhanced CT images of articular cartilage could reflect the GAG content within the cartilage by allowing measurement of the concentration of anionic iodine–based contrast agent accumulated in the cartilage. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424615 Thu, 17 Nov 2011 05:00:00 +0100 5424615 http://www.medworm.com/index.php?rid=5424614&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F796%3Frss%3D1 Conclusion: With GBCA, tumor rCBV can be underestimated without preload and becomes dose dependent with preload correction. Conversely, ferumoxytol provides consistent assessment of tumor rCBV and antiangiogenic therapy efficacy. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424614 Thu, 17 Nov 2011 05:00:00 +0100 5424614 http://www.medworm.com/index.php?rid=5424613&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F787%3Frss%3D1 Conclusion: Integration of lower extremity CT angiography into multiphasic whole-body trauma imaging is feasible, helps detect clinically relevant vascular injuries, and results in diagnostic image quality in the majority of patients. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11100604/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424613 Thu, 17 Nov 2011 05:00:00 +0100 5424613 http://www.medworm.com/index.php?rid=5424612&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F779%3Frss%3D1 Conclusion: A high-pitch spiral CT coronary angiographic protocol should be applied in patients with regular and low (<55 beats per minute) heart rates; a sequential protocol is preferred in all others. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110606/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424612 Thu, 17 Nov 2011 05:00:00 +0100 5424612 http://www.medworm.com/index.php?rid=5424611&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F771%3Frss%3D1 Conclusion: Coronary MR angiography is a reproducible and repeatable noninvasive method for detecting significant differences in coronary distensibility between patients with DM and healthy aging control subjects. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424611 Thu, 17 Nov 2011 05:00:00 +0100 5424611 http://www.medworm.com/index.php?rid=5424610&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F762%3Frss%3D1 Conclusion: Performance is affected when change from comparison mammograms is noted. Without change, sensitivity is low and specificity is high. With change, sensitivity is high, with a high false-positive rate (low specificity). Further work is needed to appreciate changes that might indicate cancer and to identify changes that are likely not indicative of cancer. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110653/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424610 Thu, 17 Nov 2011 05:00:00 +0100 5424610 http://www.medworm.com/index.php?rid=5424609&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F752%3Frss%3D1 Conclusion: At 3T, 3D MR spectroscopic imaging yields high diagnostic sensitivity and specificity for discrimination of benign and malignant breast lesions within reasonable measurement times. This technique allows the study of heterogeneous and multicentric breast tumors and simplifies acquisition planning. © RSNA, 2011 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424609 Thu, 17 Nov 2011 05:00:00 +0100 5424609 http://www.medworm.com/index.php?rid=5424608&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F744%3Frss%3D1 Conclusion: The fluctuation of breast density measured at MR imaging during a menstrual cycle was around 7%. The results may help the design and interpretation of future studies by using the change of breast density as a surrogate marker to evaluate the efficacy of hormone-modifying drugs for cancer treatment or cancer prevention. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110506/-/DC1 (Source: Radiology) Radiology journals http://www.medworm.com/rss/comments.php?id=5424608 Thu, 17 Nov 2011 05:00:00 +0100 5424608 http://www.medworm.com/index.php?rid=5424607&cid=s_36281_37_f&fid=36281&url=http%3A%2F%2Fradiology.rsna.org%2Fcgi%2Fcontent%2Fshort%2F261%2F3%2F735%3Frss%3D1 Conclusion: The diagnostic accuracy of breast MR imaging is better in more aggressive than in less aggressive cancers.
