ReviewImaging of acute and emergent genitourinary conditions: what the radiologist needs to know.
Acute and emergent genitourinary conditions require accurate and rapid diagnosis to minimize patient morbidity and mortality. ⋯ Radiologists' familiarity with the various conditions of the urinary system and of the male and female reproductive organs is important given the widespread use of imaging for the diagnosis of common clinical entities presenting to the emergency department.

Comparative StudyCT of Anatomic Variants of the Paranasal Sinuses and Nasal Cavity: Poor Correlation With Radiologically Significant Rhinosinusitis but Importance in Surgical Planning.
The purpose of this study was to determine the incidence of sinonasal anatomic variants and to assess their relation to sinonasal mucosal disease. ⋯ Analysis of every routine CT scan of the paranasal sinuses obtained for sinusitis or rhinitis for the presence of different anatomic variants is of questionable value unless surgery is planned.

Controlled Clinical TrialT2* relaxation time of acetabular and femoral cartilage with and without intraarticular gadopentetate dimeglumine in patients with femoroacetabular impingement.
The purpose of this study was to assess whether the presence of intraarticular gadopentetate dimeglumine during clinical MR arthrography significantly alters the T2* relaxation time of hip articular cartilage in patients with femoroacetabular impingement. ⋯ The results indicate that intraarticular injection of gadopentetate dimeglumine according to the protocol described in this study has little effect on the T2* of femoral and acetabular cartilage. The results suggest that T2* mapping can be safely performed as an addition to a standard clinical hip imaging protocol that includes gadopentetate dimeglumine administration.

Chemoembolization of recurrent hepatoma after curative resection: prognostic factors.
The long-term prognosis after hepatic resection for the treatment of hepatocellular carcinoma (HCC) has been disappointing because of the high recurrence rates in the remnant liver, which constitutes the major cause of death. The purpose of this study was to identify the prognostic factors for overall survival after transarterial chemoembolization (TACE) in recurrent HCC after the initial curative surgical resection. ⋯ TACE appears to be an effective treatment of patients who experienced a recurrence after curative HCC resection. An initial solitary HCC, a solitary recurrence, and recurrent tumor mass 5 cm or smaller are statistically significant independent prognostic factors for survival.

Projected Effects of Radiation-Induced Cancers on Life Expectancy in Patients Undergoing CT Surveillance for Limited-Stage Hodgkin Lymphoma: A Markov Model.
Patients with limited-stage Hodgkin lymphoma (HL) undergo frequent posttreatment surveillance CT examinations, raising concerns about the cumulative magnitude of radiation exposure. The purpose of this study was to project radiation-induced cancer risks relative to competing risks of HL and account for the differential timing of each. ⋯ Given the low rate of radiation-induced cancer deaths associated with CT surveillance, modest CT benefits would justify its use in patients with limited-stage HL.
