"An experiment showed that a novice could be subtly guided to follow an expert’s scanpath across a mammogram and that this subtle nudging improved the novice’s accuracy. The experimental results will be presented at the Eye Tracking Research & Application Symposium this March. Grimm and her colleagues say the technique, should it prove durable, is widely applicable to visual search tasks. Not only might it improve the reading of mammograms and other types of medical images, such as MRIs and PET scans, but it might also be used to improve the accuracy of airport screening and learning in virtual environments.&...

This is a plain CXR film of 73 year old referred to us with clinical suspicion of pulmonary embolism. Chest xray findings are suggestive, with elevated right hemidiaphragm, pleural effusion and rounded wedge shaped opacity showing convexity towards hilum, may indicate the classical hampton's hump. Lesser opacification and pleural effusion is noted in left side as well. Possibility was suggested and CT angiography was recommended.

There is evidence of mild prominence of the small bowel loops and localized dilated loop in the right iliac fossa along with air fluid level, which may be an indirect sign of appendicitis. This patient was followed up and turned out to be acute appendicitis. Still a lot can be diagnosed on Plain films if you look for them.
Other radiological signs for acute appendicitis: 1) Fluid levels localized to the caecum and terminal ileum, indicating inflammation in the right lower quadrant, 2) Localized ileus with gas in the cecum, ascending colon and terminal ileum, 3) Increased soft tissue density of the right lower quadra...

(ATLANTA) -- CNN recently published an article on how Kayt Sukel had an orgasm in the MR scanner. Kayt Sukel is a passionate science writer and the author of "Dirty Minds: How our brains influence love, sex and relationships" - an edgy, irreverent book that examines all the ways our neurons can wreak havoc with our hearts.
Kayt starts by saying "Let me just get this out of the way upfront: I had an orgasm in a functional magnetic resonance imaging (fMRI) scanner. That is, as background research for my book, "Dirty Minds: How our brains influence love, sex and relationships," I participated in a study at Rutgers University ...

Benign Versus Atypical/Malignant Meningiomas on DWIEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Benign meningiomas have a variable appearance on diffusion-weighted images, they tend to have higher Dav values compared with normal brain, with the exception of densely calcified or psammomatous meningiomas, which may have a low Dav. Furthermore, the average Dav values of malignant and atypical meningiomas are significantly lower compared with benign meningiomas. It seems that the quantification of the diffusion constant may reliably predict the histopathologic features of meningiomas before resection, useful because atypical and malignant meningiomas are more prone to recurrence and aggressive growth.

Many tumors involving the axial skeleton can be expansile, have low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and involve the entire vertebral body. These imaging characteristics are nonspecific. Minibrain appearance has been found characteristic of Plasmacytoma. The characteristic appearance of thickened cortical struts is probably a result of a stress phenomenon from the lytic process of the plasmacytoma forcing the remainder of the bone to increase thickness as a compensatory response to weakening bone.

Discuss or comment on this article.
FDA told physicians to stop using the CardioGen-82 some time back after identifying an increased risk of radiation exposure, Following which it was withdrawn. Now US FDA says that "improper usage" of the generator at certain sites is the likely cause of radiation exposure to patients and not faulty devices. According to them increased radiation exposure seen at specific sites was likely was due to the administration of CardioGen-82 generator eluates that contained excessive concentrations of strontium-82 (Sr-82) and strontium-85 (Sr-85).

In response to radiology residents sharing answers on their certification exams, the American Board of Radiology (ABR) is implementing a new testing procedure that relies less on memorization of facts and more on testing concrete skills. Previous CNN investigation revealed to the public what appears to be a well-known fact in the radiology community: Residents preparing for their board certification exams often get a leg up by studying past questions, which come from a repository contributed to by past test-takers. In the new system, tests will assess the doctors' abilities to actually interpret imaging studies and pe...

This is a 33year old male and had running injury 3 weeks back followed by inability to plantar flex the ankle. MRI was suggested. There is evidence of discontinuity and altered signal intensity, fluid collection in relation to the myotendinous junction of the tendoachilles with gap measuring 1.4cm with retraction of muscles. Likely consistent with complete tendoachilles tear.

What should we do if the organization that we work in has inadequate software and work-stations for angiographies or some studies and yet force the radiologist on pay-roll to make the report. Simply said, you should refuse but being within an organization like this and saying no to these suboptimal images and lack of state of the art facilities, sometimes become difficult. Balance is between relationship and ethics at times. What should you do when such a situation arise?

The American College of Radiology (ACR) is deeply troubled by implications of a recent CNN report involving the American Board of Radiology (ABR) certification examinations. While the ABR and the ACR are separate and independent organizations, the College is comprised of board-certified radiologists, radiation oncologists, interventional radiologists, nuclear medicine physicians and medical physicists, and therefore has a legitimate interest in the CNN portrayal of radiology board certification.
The most troubling aspect of this report is the implication that all radiologists who pass these examinations are "cheaters."...

Multivesicular cysts manifest as well-defined fluid collections in a honeycomb pattern with multiple septa representing the walls of the daughter cysts (7). Daughter cysts appear as cysts within a cyst. When daughter cysts are separated by the hydatid matrix (a material with mixed echogenicity), they demonstrate a “wheel spoke” pattern. The matrix represents hydatid fluid containing membranes of broken daughter vesicles, scolices, and hydatid sand. Membranes may appear within the matrix as serpentine linear structures, a finding that is highly specific for hydatid disease. Spotter case contributed by: Indra Neil M...

"Not all of these deals are bad, but doctors should at least have an attorney review the terms so that they're protected. Doctors can also get burned by buying expensive equipment."

ABR’s EXAM SECURITY

In the many comments on the CNN story on test recall questions, the same questions are being asked. It is important that we make clear the following points:
Our overriding goal is to ensure good patient care and for our patients to feel confident that the physicians who care for them have the knowledge and skills to do so. To that end, there are many checks and balances in place beyond these tests.
We are moving to a completely new test, given solely on a computer, to eliminate concerns that have been raised over the potential of bias in oral examination...

Horse shoe kidney- described classically as : Large kidney mass consisting of two lateral lobes and an isthmus of apparently normal kidney tissue between the lower lobes. Each lateral lobe possessed a hilum on its anterior surface from which the calices emerged to form the ureter. The ureters passed downward over the anterolateral surface of the lower poles, then across the terminal parts of the common iliac vessels, to enter the bladder in the usual manner. Though Aorta and IVC appear normal with no accessory renal arteries, however thin sections required to comment on the same. Both kidneys were in symmetrical ptosi...

Image Courtesy TMONews.comIt seems I was part of an experiment and didn't completely realize it.One of our in-house transcriptionists as been using speech-recognition in what I call "editor mode". In other words, my dictation is run through an SR engine (I don't know which one) to provide the first draft of the report. She then edits it while listening to the dictation, and places the final report on the RIS for my review. This should give us the best of both worlds, the speed of SR and the accuracy of a human.Except it doesn't work.The particular transcriptionist is really superb at what she does, and before this li...

Discuss or comment on this article.
An important clinical application of dual-energy CT is to generate pre-contrast images from a post-contrast dual-energy scan so that the pre-contrast scan can be avoided, potentially reducing radiation dose. The image quality and dose saving of Virtual non contrast technique depend on three factors: dose partitioning between the low- and high-energy scans, patient size, and spectra separation.

Periosteal reaction for the Radiology ResidentsEmail this article to a colleague.

Periosteal reaction for the residents, this is what you should keep in mind while reporting a skeletal case.
With slow-growing processes, the periosteum has time to respond to the process. Therefore, it can produce new bone just as fast as the lesion is growing-solid, uninterrupted periosteal reaction.
With rapidly growing processes, the periosteum cannot produce new bone as fast as the lesion is growing. Therefore, rather than a solid pattern of new bone formation, we see an interrupted pattern. This may result in a pattern of one or more concentric shells of new bone over the lesion-lamellated or "on...
