Transrectal sonography clearly visualizes prostate anatomyTransrectal ultrasound provides clear images of the prostatic anatomy and accurate guidance for prostate biopsy.1 The technique has become useful for the evaluation of patients with prostatic disease, but its success depends greatly on individual operators. It is important for radiology staff to understand the correct approach to prostate scanning and biopsy procedures, as well as the indications and limitations.

Vessel imagers focus on plaque characterizationPlaque rupture is the main cause of acute coronary syndromes, which are associated with high mortality and morbidity. The prevalence of plaque rupture in acute coronary syndrome is more than 70%.1 Rupture-prone plaques are characterized by a large core of extracellular lipid with a thin fibrous cap (Figure 1). Inflammation, particularly in the plaque shoulder, causes the fibrous cap to thin and results in disruption of the atherosclerotic plaque.

RFA and cryoablation expand treatment of hepatic tumorsAblative techniques have greatly improved physicians' ability to definitively treat patients with primary and secondary hepatic tumors. These techniques include radiofrequency ablation (RFA) and cryoablation, as well as newer microwave and laser ablation methods. Ablation devices, used either alone or combined with hepatic resection, have made it feasible to treat patients with bilobar lesions and those who would not tolerate liver resection due to underlying comorbidities.

Imaging modalities shed light on intracranial cystsAny fluid-filled cavity or sac that is lined by an epithelium is a cyst, and intracranial cystic lesions are a common finding on CT and MR imaging of the brain.1,2 These lesions contain either cerebrospinal fluid, fluid that is similar to CSF, mucus, or proteinaceous fluid. They are lined by epithelial cells, inflammatory cells, or glial cells. The attenuation characteristics of the cyst on CT and MRI and the contrast enhancement patterns depend on the cyst's contents and the composition of the wall.
