Sonographic and CT features of splenogonadal fusion.

Splenogonadal fusion is a rare congenital anomaly characterized by fusion of splenic tissue to the gonad. Although more than 150 cases have been described in the literature, there are only anecdotal reports of the diagnosis of this entity before surgery. Preoperative recognition of this anomaly permits avoidance of radical surgical procedures such as orchiectomy.

Visualization techniques in computed tomographic coronary angiography.

Cardiac computed tomography (CT) scans can produce enormous datasets (>3,000 images), making traditional axial image interpretation un-workable. Previously existing and new techniques including multiplanar reformats, volume rendering, maximum intensity projections, curved multiplanar reformats, and "4D" (time-resolved) methods have all been used to increase diagnostic accuracy and reduce interpretation times. The methods and applications of these techniques to cardiac anatomy will be reviewed and discussed with an eye toward practical film interpretation.

Effect of contrast concentration, tube potential and reconstruction kernels on MDCT evaluation of coronary stents: an in vitro study.

Introduction: To evaluate effect of different kVp, reconstruction kernels and contrast concentrations on stent luminal diameter measurements and luminal contrast attenuation values.

Methods: Two metallic coronary stents (2.75 mm and 3.

Multidetector-row CT: economics and workflow.

With rapid evolution of multidetector-row CT (MDCT) technology and applications, several factors such as technology upgrade and turf battles for sharing cost and profitability affect MDCT workflow and economics. MDCT workflow optimization can enhance productivity and reduce unit costs as well as increase profitability, in spite of decrease in reimbursement rates. Strategies for workflow management include standardization, automation, and constant assessment of various steps involved in MDCT operations.
