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.

MSCT assists in renal cell cancer workupRenal cell cancer is the most frequently encountered malignant tumor in the kidney. Over 30,000 new cases are diagnosed annually in the U.S. Many cases are now detected incidentally, as a result of the widespread use of multislice CT. MSCT usage is also redefining diagnostic workup of renal lesions and facilitating renal cell cancer staging.

No premedication equals fewer staff, more patientsCoronary CT angiography is commonly performed using beta blockers to slow the heart rate and reduce motion artifacts in the images, thereby improving diagnostic accuracy. Oral metoprolol is often prescribed one hour prior to the procedure. Intravenous metoprolol may be given immediately prior to the procedure as an alternative or if oral beta blocker alone did not achieve adequate heart rate control.
