E-prescribing could help control medical radiation exposureThere has been considerable discussion on the federal stimulus program and the impact it will have in bringing about an improved patient care model through the use of technology. This anticipates care providers having access to electronic health records (EHRs) that can communicate, or “interoperate,” with other health providers and health systems so a complete record of all a patient’s episodes of care, including pharmaceutical records, are available in real-time for physician review. As I explain below, these mechanisms could be used to help monitor and control medical radiation exposure.

Reliable In-Stent Lumen Visualization With Dual Source CT Coronary AngiographyA 58-year-old man with a history of hypertension and hypercholesterolemia was admitted to the hospital with symptoms of suspected stable angina pectoris. The patient was referred to conventional coronary angiography after a positive exercise-ECG test. Conventional angiography showed significant stenoses at the level of the proximal right coronary artery (RCA) and the proximal left anterior descending coronary artery (LAD). Percutaneous intervention was undertaken and one bare-metal stent in the RCA and two overlapping bare-metal stents in the LAD were successfully implanted. The patient was referred to follow-up CT coronary angiography after 18 months.

Ovarian lesions pose diagnostic dilemmasThe main objective of imaging patients with symptoms suggestive of ovarian lesions is to distinguish benign findings from malignant disease. Masses can be characterized with a variety of noninvasive imaging techniques, including transabdominal and transvaginal ultrasound, CT, and MRI. Each of these modalities has its advantages and limitations.

Coronary CT angiography saves lives and money: 20,000-plus cases prove itQuestions remain from practitioners, payers, and administrators regarding the economic impact of coronary CT angiography on established diagnostic modalities and the effects on reimbursement within imaging. To address these concerns, we have developed the CCTA Data Registry, which now consists of more than 20,000 cases. Preliminary results indicate that coronary CTA is being utilized appropriately and affects savings for the healthcare system.

CT and MRI help evaluate adrenal gland disordersThe adrenal glands are paired retroperitoneal endocrine organs. They are thin, inverted Y- or V-shaped soft tissue structures and have flat or concave margins. The vertical length of each gland may be anywhere from 2 to 4 cm. Their “limbs” are approximately 0.4 cm thick in axial cross-section, which is roughly as thin as the adjacent diaphragmatic crus.

Smart searching enables radiologists' e-learningThe Internet has become an invaluable tool to radiology. New media formats make it easy to stay up to date. In addition to browsing key websites, radiologists can sign up for e-mail newsletters, RSS feeds, and podcasts, and they can access these textual, visual, and auditory data via a variety of gadgets.

Europe's PACS users must embrace open sourceWhen EuroPACS was founded in the early 1980s, PACS development and implementation were at the frontier of technical innovations in medicine. Commercial systems and vendor solutions did not exist. EuroPACS annual meetings were a unique opportunity to meet the pioneers in the field and learn from their work.

CT report that includes all data boosts benefitsAccurate and reproducible assessment of left ventricular function is crucial for differential diagnosis, risk stratification, treatment planning, and predicting prognosis in patients with heart disease. Evaluation of global and regional LV wall motion, valvular function, myocardial mass, and, in some cases, right ventricular function produces valuable ancillary pieces of clinical information that can be obtained from a contrast-enhanced multislice CT scan.
