Sonographic diagnosis of appendicitis: A pictorial essay and a new diagnostic maneuver.

While many cases of appendicitis are easy to diagnose clinically, a significant number need further workup in the form of imaging. Ultrasound and CT are both used extensively to diagnose or exclude appendicitis, or arrive at an alternate diagnosis. Ultrasound has many advantages but can be a difficult modality to use due to, among other reasons, the anatomical variations in appendicial location.

Nuclear Cardiology in Asia.

Nuclear cardiology for patients with ischemic heart disease and cardiac failure is expanding in Asia, although quite heterogeneously. In Asia, Israel showed the highest utilization with more than 1000 scans/100,000 inhabitants a year followed by Korea, Japan, UAE, Turkey, Australia (250-999 scans/100,000). Saudi Arabia, Kuwait, Jordan, Lebanon, Iran, and Pakistan practiced 60-99 scans/100,000.

Image perception and interpretation of abnormalities; can we believe our eyes? Can we do something about it?

The radiologist's visual impression of images is transmitted, via non-visual means (the report), to the clinician. There are several complex steps from the perception of the images by the radiologist to the understanding of the impression by the clinician. With a process as complex as this, it is no wonder that errors in perception, cognition, interpretation, transmission and understanding are very common.

Automated classification of liver disorders using ultrasound images.

This paper presents a novel approach for detection of Fatty liver disease (FLD) and Heterogeneous liver using textural analysis of liver ultrasound images. The proposed system is able to automatically assign a representative region of interest (ROI) in a liver ultrasound which is subsequently used for diagnosis. This ROI is analyzed using Wavelet Packet Transform (WPT) and a number of statistical features are obtained.

Implementing sentinel lymph node biopsy programs in developing countries: challenges and opportunities.

Background: Sentinel lymph node biopsy (SLNB) is the accepted standard of care in early-stage breast cancer and cutaneous melanoma. This technology is accurate for nodal staging and determining the prognosis of these patients. There are several randomized controlled trials confirming the accuracy of this technique and confirming its role in reducing morbidity and improving quality of life.
