Case of double-outlet right ventricle after repair with pulmonary arteriovenous malformations using cardiac CT.

We present a case where cardiac CT clearly defines the complex anatomy of a 22 year old man with double outlet right ventricle who is status bilateral bidirectional Glenn and Fontan conduit. This case also shows the association of pulmonary arteriovenous malformations with Fontan and Glenn procedures.

Detection and reproducibility of mental stress-induced myocardial ischemia with Tc-99m sestamibi SPECT in normal and coronary artery disease populations.

Background: Mental stress-induced ischemia, as detected by radionuclide studies, has yielded reversible ischemia in only 30% to 60% of patients with exercise-induced ischemia. Little is known about the reproducibility of myocardial perfusion imaging in detecting mental stress-induced ischemia. The purpose of this study was to further evaluate the occurrence and reproducibility of mental stress-induced ischemia in patients with coronary artery disease (CAD) and in normal control subjects with a low likelihood of CAD by using sestamibi single photon emission computed tomography (SPECT) imaging.

Sequential dermal-peritumoral radiocolloid injection for sentinel node biopsy for breast cancer: the University of Florida experience.

Although sentinel lymph node (SLN) biopsy is rapidly becoming the standard of care for small breast cancers the optimal radiocolloid injection technique remains controversial. We report our experience with sequential dermal-peritumoral radiocolloid injection that takes advantage of both techniques. One hundred eighteen patients with clinical stage T(is), T1, T2 and N0 breast cancer underwent SLN biopsy at the University of Florida.
