PURPOSE To identify computed tomographic (CT) findings that distinguish perirenal liposarcomas from exophytic angiomyolipomas. MATERIALS AND METHODS We identified CT scans of 20 patients (13 women and 7 men; mean age, 63 years) with either perirenal liposarcoma (n = 11) proven at histopathology or large exophytic angiomyolipomas (n = 9) determined by(More)
PURPOSE To evaluate a histogram analysis method for differentiating adrenal adenoma from metastasis at computed tomography (CT). MATERIALS AND METHODS In a retrospective review of 2 years of clinical CT records, 223 adrenal adenomas in 193 patients (115 with contrast material-enhanced CT, 43 with unenhanced and enhanced CT, and 35 with unenhanced CT) and(More)
PURPOSE To retrospectively determine a biometric algorithm for calculating relative lung volume in fetuses with normal lungs and of a wide range of gestational ages by using proved independent variables and to retrospectively investigate the use of this algorithm in fetuses with pulmonary hypoplasia. MATERIALS AND METHODS Total lung volume (TLV) was(More)
PURPOSE To compare cancer recurrence outcomes on the basis of compliant semiannual versus noncompliant annual ipsilateral mammographic surveillance following breast conservation therapy (BCT). MATERIALS AND METHODS A HIPAA-compliant retrospective review was performed of post-BCT examinations from 1997 through 2008 by using a deidentified database. The(More)
RATIONALE AND OBJECTIVES Renal medullary hypoxia is frequently implicated in renal dysfunction, and urinary oxygen tension (PO(2)) in the renal pelvis can be used as a surrogate for the adjacent renal medullary oxygenation. We sought to assess the feasibility of magnetic resonance (MR) quantification of urinary PO(2) in humans. MATERIALS AND METHODS The(More)
This study was a retrospective single-institutional study approved by the Committee on Human Research and was HIPAA compliant. A waiver for informed consent was granted. The purpose of the study was to evaluate the effect of four peak voltage settings on the in vitro conspicuity of gallstones in an anthropomorphic phantom at computed tomography (CT). An(More)
OBJECTIVE Our aim was to determine the supplemental value of MRI in fetal abdominal disease detected on prenatal sonography. CONCLUSION Our preliminary results suggest the primary supplemental value of MRI relative to sonography in fetal abdominal disease lies in improved tissue characterization rather than in improved anatomic characterization.
OBJECTIVE The objective of this article is to provide a practical review of the incremental benefit of MRI in the assessment of adnexal masses in pregnancy. CONCLUSION MRI can assist sonographic assessment of adnexal masses in pregnancy by depicting the characteristic findings of exophytic leiomyoma, red degeneration of leiomyoma, endometrioma,(More)
OBJECTIVE To investigate the MRI findings of massive ovarian edema in pregnancy. CONCLUSIONS Asymmetric ovarian enlargement with a teardrop configuration and T2 hyperintensity with or without T1 hyperintensity appear characteristic of massive ovarian edema in pregnancy, potentially facilitating nonoperative diagnosis and expectant management.
