Is magnetic resonance imaging safe for patients with retained metal fragments from combat and terrorist attacks?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: conducting 1.5T MRI examinations is safe in patients with retained metal fragments from combat and terrorist attacks not in the vicinity of vital organs. However, caution is advised. PMID: 19912071 [PubMed - as supplied by publisher] (Source: Acta Radiologica)

Infratentorial oligodendrogliomas: Imaging findings in six patients.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Although infratentorial oligodendrogliomas did not show characteristic imaging findings, there was a tendency toward multifocal heterogeneous enhancement and absent or mild mass effect of infiltrative lesions. Infratentorial oligodendrogliomas may be more malignant than supratentorial oligodendrogliomas. PMID: 19912073 [PubMed - as supplied by publisher] (Source: Acta Radiologica)

Physiological fluctuation of (99m)tc-sestamibi uptake in normal mammary glands: a systematic investigation in female rats.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Tc-99m-sestamibi uptake fluctuates significantly in normal mammary tissues in synchrony with the female reproductive cycle, and peaks in the proestrous phase in rats, which is equivalent to the early to mid-follicular phase in the human menstrual cycle. This finding will likely benefit the detection of breast lesions that may otherwise be obscured by fluctuating background signals in surrounding normal breast tissues.

Efficient use of automatic exposure control systems in computed tomography requires correct patient positioning.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: This study demonstrates that patient centering markedly affects the efficacy of AEC function and that tube current changes vary between scanners. Tube position when acquiring the scout projection radiograph is decisive for the direction of the mAs change. Off-center patient positions cause errors in tube current modulation that can outweigh the dose reduction gained by AEC use, and image quality is affected.

Tears of the supraspinatus tendon: assessment with indirect magnetic resonance arthrography in 67 patients with arthroscopic correlation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Indirect MR arthrography is highly accurate in the diagnosis of full-thickness rotator cuff tears. However, the diagnosis of partial-thickness tears with indirect MR arthrography remains faulty, because exact demarcation of degenerative change and partial rupture is difficult. On the basis of the above findings, we do not recommend indirect MR arthrography on patients for whom rotator cuff disease is suspected clinically.

Diagnostic value of multislice computed tomography and magnetic resonance imaging in the diagnosis of retroperitoneal spread of testicular cancer: a literature review.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Testicular cancer is the most frequent malignant disorder in men aged 15-35 years. Generally, diagnosing and follow-up include computer tomography (CT) examinations to detect possible retroperitoneal spread (abdomen and pelvis), resulting in at least eight CT examinations. This patient group is thereby exposed to a non-neglectable radiation dose, increasing the risk of future radiation-induced secondary cancer. This is especially problematic in potentially surgically cured patients with stage 1 testicular cancer. Thus, it can be beneficial to substitute CT with magnetic resonance imaging (MRI), provided there is valid ...

Comparison of computed tomography histogram analysis and chemical-shift magnetic resonance imaging for adrenal mass characterization.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: CT histogram analysis method using a 10% negative pixel threshold on unenhanced CT had a good sensitivity and perfect specificity for the differentiation of adrenal adenomas from non-adenomas. In spite of the good results obtained with the CT histogram analysis method, chemical-shift MRI using adrenal-to-spleen chemical-shift ratio and adrenal signal intensity index formulas had a higher sensitivity and could help in the characterization of adrenal masses appearing indeterminate by CT histogram analysis.

Magnetic resonance imaging findings of ovarian stromal hyperthecosis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report a case of ovarian stromal hyperthecosis with particular regard to magnetic resonance (MR)-pathologic correlation. At initial MR imaging, the central areas of the bilateral ovarian masses showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images, while the peripheries of the bilateral masses showed isointensity to myometrium on T1-weighted images and heterogeneous signal intensities on T2-weighted images. At 15 days after the initial MR imaging examination, a second MR imaging demonstrated shrinkage of the bilateral ovarian masses. Change in the peripheries to predominantly isointensity t...

Save this article to My Clippings. Discuss or comment on this article.
We present findings in a juvenile patient with surgically corrected transposition of the great arteries (d-TGA) and aortic coarctation. For the first time, the complex flow patterns in the PA following d-TGA were visualized. Morphologically, a slight asymmetry of the PA was found, with considerable impact on vascular hemodynamics, resulting in diastolic retrograde flow in the larger vessel and diastolic filling of the smaller PA. Additionally, increased flow to the supraaortic vessels was found due to aortic coarctation. PMID: 19639472 [PubMed - as supplied by publisher] (Source: Acta Radiologica)

Hilar cholangiocarcinoma is associated with a dismal prognosis; however, curative resection may offer a chance of cure. Various factors should be considered in the surgical planning for curative resection.

Diffusion-Weighted Magnetic Resonance Imaging in Cervical Lymphadenopathy: Report of Three Cases of Patients with Bartonella henselae Infection Mimicking Malignant Disease.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Diffusion-weighted MR imaging is a potential technique for differentiation between benign and malignant lymph nodes. However, lympadenopathy caused by Bartonella henselae infection shows low ADC values in diffusion weighted MRI as typically seen in malignant disease.

Sonographic Changes after Removing All Benign Breast Masses with Sonographically Guided Vacuum-Assisted Biopsy.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The total removal of benign breast masses using sonographically guided VAB frequently produces changes on follow-up sonography after 6 months. Although these changes failed to show statistical significance with procedural factors, a larger dedicated study is needed.

Efficient Use of Automatic Exposure Control Systems in Computed Tomography Requires Correct Patient Positioning.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: This study demonstrates that patient centering markedly affects the efficacy of AEC function and that tube current changes vary between scanners. Tube position when acquiring the scout projection radiograph is decisive for the direction of the mAs change. Off-center patient positions cause errors in tube current modulation that can outweigh the dose reduction gained by AEC use, and image quality is affected.
