About Telesonography

According to a recent article in AJR-The Feasibility of Real-Time Transmission of Sonographic Images from a Remote Location over Low-Bandwidth Internet Links: A Pilot Study. AJR 2007; 188:W219-W222
"Authors sought to show that sonography can be performed in teleconference settings, "telesonography," in which a remotely located sonography interpreter can monitor the examination in real-time and guide the examiner with voice commands while the patient simultaneously undergoes imaging, albeit at low resolution, thus helping to overcome the lack of trained operators in certain areas. According to them, this system of image transfer offers the potential for sonography to be performed at a remote underdeveloped region and interpreted in real-time at a distant site by trained radiologists, thereby extending the presence of physicians in virtual space.

Tunneled Coronary Artery

"Tunneled coronary arteries are clinically relevant due to their association with myocardial ischemia.The coronary arteries may dip into the myocardium for varying lengths and then reappear on the heart surface. The muscle overlying the intramyocardial segment of the epicardial coronary artery is termed as myocardial bridge and the artery coursing within the myocardium in called a tunneled artery."
One of the conditions where CT coronary angiography can give mor einformation than angiography.

Increasing work load leaves Radiologists fatigued

"Today's radiologist is a multitasking technology wizard, responding to pages, phone calls and personal consults with clinicians while reviewing plain films, MRIs and CTs and editing their voice recognition-developed dictations.This is a far cry from the early 1990s when we didn't even carry pagers.Not only has the demand for imaging increased in the past decade – producing a definite increase in volume of studies to be performed and interpreted – imaging plays an increasingly pivotal role in the diagnosis, triage and management of patients, resulting in a greater sense of urgency and stress for radiologists during the workday and on call."

Lancet-Top Ten Free Software for Doctors

"Computers and the internet have an increasingly important role in medicine, and have become integral to modern care. For instance, it has been suggested that search engines can help doctors diagnose difficult cases. The internet is not only a font of factual knowledge but also a source of useful software, much of it free (freeware). These are our “top ten” free utilities for computers running the Windows operating system. They are small programs that facilitate common computing tasks and which we use regularly to supplement standard commercial software."

Cochrane Library now freely available in India

The Cochrane Library is now freely available to all residents of India with internet access thanks to funding from the Indian Council of Medical Research (ICMR). Through several provisions and funding schemas, the Cochrane Library is currently freely available in many geographic areas of the world including Australia, Norway, Ireland, parts of Canada and many other countries, regions and territories. For a full list, look under "Access to Cochrane" on the Cochrane Library's homepage via John Wiley & Sons. From 29 January 2007 the Cochrane Library will be freely available to all residents of India with internet access thanks to funding from the Indian Council of Medical Research (ICMR) (, and work of the South Asia Cochrane Netork ( More than a thousand million people will now have the opportunity to access the high-quality, independent evidence for healthcare decision-making found in the Cochrane Library. Here is a link to an article in the Indian newspaper,

MRI better than CT for initial evaluation of stroke

"A multicenter prospective trial involving 1210 patients in Europe has found that the odds of a favorable clinical outcome were one-third higher for acute stroke patients who received diffusion-perfusion MRI to determine the appropriateness of tPA thrombolysis than patients assessed with conventional noncontrast CT. Results drawn from the Safe Implementation of Thrombolysis in Stroke trial were presented at International Stroke Conference in San Francisco."

Supraclinoid Aneurysm- A Case Report

Case Submitted by Dr MGK Murthy Sr Consultant Teleradiology Providers

Case Details and Discussion
55 yr old lady complains of chronic headache of 10 yrs duration with increasing severity
she is normotensive and has no neurological deficit Routine MRI shows well defined regular heterogenous altered signal intensity extraaxial lesion in left paracavernous and supraclinoid locations with an intensely enhancing nodule within on contrast as well as hypointense periphery with no significant perilesional oedema- likely to be partially thrombosed internal carotid giant aneurysm with thrombus within. DSA is the solution. At times Meningimas which are cystic, haemangioblstomas and pilocytic astrocytomas could present a diagnostic difficulty. However intense nodular enhancement, lack of perilesional oedema, chronic headache of long duration with no deficit are supportive of aneurysm. Supraclinoid component is suggested as intracavernous ICA appears compressed and shows normal flow void.

MRI features in Placental Invasion

The value of specific MRI features in the evaluation of suspected placental invasion by Lax A et al in Magn Reson Imaging 2007 Jan;25(1):87-93. Epub 2006 Nov 14 points out that MRI can be a useful adjunct to ultrasound in diagnosing placenta accreta prenatally. Three features that are seen on MRI in patients with placental invasion appear to be useful for diagnosis: uterine bulging; heterogeneous signal intensity within the placenta; and the presence of dark intraplacental bands on T2W imaging.

A New Radiology Teaching File with a difference

"The aim of this website is to be a completely free radiology education resource. Dr Simon has developed software which allows the user to view entire CT and MRI datasets over a broadband connection - in order to be able to test themselves in a real life environment - rather than with static images forun in many teaching websites.
