Single coronary artery Left (SCA L)-Right coronary artery arising from mid-left anterior descending coronary artery: New variant of Lipton classification (SCA L-II) diagnosed by computed tomographic angiography.

Isolated single coronary artery (SCA) is a rare anomaly. Current classification of left and right is further classified based on the course of the anomalous vessel. We report two SCA L cases where right coronary artery (RCA) arose from mid-left anterior descending coronary artery (LAD).

Radiography of cardiac conduction devices: a comprehensive review.

Radiology plays a crucial role in initial assessment and follow-up of cardiac conduction devices (CCDs). At least 1 million patients in the United States have permanent CCDs, which comprise pacemakers and implantable cardioverter-defibrillators. Chest radiography is unique because it is the only imaging modality that allows evaluation of the physical integrity of CCD leads.

Pancreatic herniation through the gastroesophageal hiatus: magnetic resonance imaging, magnetic resonance cholangiopancreatography, and computed tomography evaluation.

A rare case of pancreatic herniation through the gastroesophageal hiatus is presented, including magnetic resonance evaluation with magnetic resonance cholangiopancreatography and magnetic resonance angiography images unique to the published literature.
