Testicular FDG Uptake on PET/CT in Patients with Lymphoma: Correlation with Age.

The purpose of this observational study was to investigate whether the standard uptake value (SUV) measurement has practical utility in distinguishing secondary testicular involvement from physiologic uptake in patients with lymphoma. A Radiology Information System (RIS) search was conducted for all PET/CT studies performed from 2010-2016 on adult male patients with a diagnosis of lymphoma. Patients with clinical or pathologic diagnosis of testicular lymphoma were excluded to undergo a separate analysis.

Establishment of normative values for the fetal posterior fossa by magnetic resonance imaging.

Objective: Suspected Dandy-Walker continuum anomalies constitute a significant percentage of prenatal cases evaluated by magnetic resonance imaging (MRI). To unify the description of posterior fossa malformations, we sought to establish objective measurements for the posterior fossa in normal fetuses between 18 and 37 weeks gestation.

Methods: T2-weighted images of normal fetal brains in sagittal projection were obtained from fetal magnetic resonance (MR) studies of normal brains performed from 2009 to 2017.

Spontaneous regression of a metastatic melanoma pulmonary deposit following biopsy.

Spontaneous complete and partial regression of metastatic melanoma is poorly understood, and is a rare phenomenon with less than 80 cases reported since 1866. Several correlations have been noted such as systemic or local infections, operative trauma, hormonal influences, nutrition and immunologic factors. We present FDG PET and CT findings in a patient with multiple pulmonary metastases of melanoma, one of which underwent regression following biopsy.
