CT, ultrasound, MR, oncologic imaging, genitourinary radiology, neoplasms of the upper urinary tract, renal infectious disease, abdominal trauma, contrast media toxicity/reactions

Research Interests
Current and ongoing research activities include evaluation of contrast reactions in patients who have received a steroid preparation.  This endeavor will aim to evaluate common risk factors shared by patients who have so called breakthrough reactions.  This may help to further redefine premedications regiments in high risk patients.  Additional research activities include clinical CT scanning of the kidneys with the use of a compression device.  The aim of this work will help to establish whether compression CT improves visualization of the collecting system and ureters over conventional urography.  Other ongoing projects include CT descriptions of idiopathic retroperitoneal fibrosis causing renal and perirenal masses, post traumatic  pseudopneumoperitoneum and continued work on extravastion injuries and extravasation detection.
