Multislice CT coronary angiography for the detection of burden, morphology and distribution of atherosclerotic plaques in the left main bifurcation.

The aim of the study was to explore the differences in plaque burden at different segments of the left main bifurcation and its relationship with the bifurcation angle using high-resolution multislice CT coronary angiography (MSCT). Patients were evaluated using a 40-row MSCT scanner. One observer assessed the localization, severity and distribution of plaques within the left main (LMCA) bifurcation, whereas another observer defined the angle.

Modified scan protocol using multislice CT coronary angiography allows high quality acquisitions in obese patients: a case report.

Nearly every cardiovascular functional imaging technique has difficulties in dealing with obese patients and MSCT-CA is not an exception. Excluding such large portion of the coronary population remains a grim limitation of the technique and requires thus a comprehensive re-evaluation. In this report, we show that excellent image quality could be achieved in a morbidly obese patient with the aid of proper management of scan protocols and bolus administration.
