PURPOSE To determine if local recurrence of prostate cancer after radiation therapy occurs at the same site as the primary tumor before treatment, using longitudinal magnetic resonance (MR) imaging and MR spectroscopic imaging to assess dominant tumor location. METHODS AND MATERIALS This retrospective study was HIPAA compliant and approved by our(More)
PURPOSE To investigate the role of endorectal MR imaging and MR spectroscopic imaging in defining the contour of treatable intraprostatic tumor foci in prostate cancer, since targeted therapy requires accurate target volume definition. MATERIALS AND METHODS We retrospectively identified 20 patients with prostate cancer who underwent endorectal MR imaging(More)
PURPOSE To describe a rapid T2*-weighted (T2*W), three-dimensional (3D) echo planar imaging (EPI) sequence and its application in mapping local magnetic susceptibility variations in 3 Tesla (T) prostate MRI. To compare the sensitivity of T2*W EPI with routinely used T1-weighted turbo-spin echo sequence (T1W TSE) in detecting hemorrhage and the implications(More)
OBJECTIVE The purpose of this pictorial essay is to review the imaging findings of acute, chronic, and tumor-related nontraumatic adrenal hemorrhage. CONCLUSION Rapid development or evolution of a nonenhancing adrenal mass or masses with an adreniform shape or high T1 signal intensity on MR images of a patient under stress or with a bleeding diathesis,(More)
This article reviews the anatomy of the prostate gland, magnetic resonance (MR) imaging techniques, and the role MR imaging in the setting of prostate cancer. Sequences discussed include T2-weighted MR imaging, proton ((1)H) MR spectroscopic imaging, diffusion-weighted MR imaging, and dynamic contrast-enhanced MR imaging. MR imaging can be applied as an(More)
PURPOSE To describe the computed tomographic (CT) appearances and clinical consequences of tumor fistulization as a complication of targeted therapy for cancer. METHODS The committee on human research approved this Health Insurance Portability and Accountability Act-compliant study and waived written informed consent. Based on the records of the senior(More)
Purpose: Prostate specific antigen levels can be normalized by the prostate volume to give a prostate specific antigen density (PSAd). Magnetic resonance imaging (MRI) can more accurately determine prostate zonal anatomy and prostate volumes compared to transrectal ultrasound, and hence may lead to more accurate PSAd measurements. Methods: Imaging and(More)
Seventy-nine consecutive patent ductus arteriosus (PDA) ligations were performed in our newborn intensive care unit (NBICU) over a four-year period. Seven infants (9%) died within one month after surgery. The deaths were not attributed to the surgery but were associated with preexisting medical complications or new intracranial hemorrhages. Significant(More)
PURPOSE To investigate the potential clinical utility of endorectal MRI-guided biopsy in patients with known or suspected prostate cancer. MATERIALS AND METHODS We prospectively recruited 24 men with known or suspected prostate cancer in whom MRI-guided biopsy was clinically requested after multiparametric endorectal MRI showed one or more appropriate(More)
PURPOSE To investigate criteria that can identify dominant treatable prostate cancer foci with high certainty at endorectal magnetic resonance imaging (MRI) and MR spectroscopic (MRS) imaging, and thus facilitate selection of patients who are radiological candidates for MR-guided focal therapy. MATERIALS AND METHODS We retrospectively identified 88(More)
