Appearance of the Upper Urinary System After Treatment.

Renal cell carcinoma and upper tract urothelial cancer are increasing in incidence. Rates of local recurrence and complications vary with the treatment modality, but the imaging appearance of recurrence and complications is similar no matter the method of local treatment. The use of contrast-enhanced, multiphase imaging is recommended to best evaluate the treatment bed for recurrence and complications.

Endovascular Management of a Ruptured Aneurysm on a Posterior Inferior Cerebellar Artery with Extradural C2-Origin: Case Report and Literature Review.

Extracranial vascular pathology uncommonly causes intracranial subarachnoid hemorrhage (SAH). Among possible lesions are aneurysms at the craniocervical junction arising from a posterior inferior cerebellar artery (PICA) with an extradural origin. We describe a case of a 55-year-old female presenting with a sudden and severe headache.

Attending Reviews of Residents Correlate with ABR Qualifying (Core) Examination Failure.

Rationale And Objectives: Since the American Board of Radiology (ABR) instituted the new system of board certification, there has been much discussion as to the test's validity. We decided to evaluate if subjective evaluation of resident performance correlated with ABR Qualifying (Core) Examination performance at this single institution.

Materials And Methods: Data regarding resident evaluation scores by attending physicians and passage of board examinations was gathered regarding residents who had taken the ABR Qualifying (Core) Examination from 2013 through 2019 for a total of 42 residents, eight of whom failed the ABR Qualifying (Core) Examination on their first attempt.

Predictors for Failing the American Board of Radiology Core Examination.

Since the American Board of Radiology (ABR) instituted its new board certification pathway, our residency program has had more residents fail the core examination than was typical with the prior pathway. We performed a single-center retrospective study to evaluate predictors of ABR core examination failure. Data regarding U.

Initial series of magnetic resonance imaging (MRI)-fusion targeted prostate biopsy using the first transperineal targeted platform available in the USA.

Objectives: To describe a step-by-step guide for using the first transperineal targeted prostate biopsy platform available in the USA.

Patients And Methods: A total of 32 men with elevated prostate-specific antigen (PSA) levels were diagnosed with a region of interest on multiparametric magnetic resonance imaging (mpMRI) between February 2017 and January 2018. The transperineal targeted prostate biopsy procedure was accomplished via a transperineal approach and used a stepper, combined with advanced mpMRI/transrectal ultrasound fusion software, to perform targeted prostate biopsy.

PET/MR in invasive ductal breast cancer: correlation between imaging markers and histological phenotype.

Background: Differences in genetics and receptor expression (phenotypes) of invasive ductal breast cancer (IDC) impact on prognosis and treatment response. Immunohistochemistry (IHC), the most used technique for IDC phenotyping, has some limitations including its invasiveness. We explored the possibility of contrast-enhanced positron emission tomography magnetic resonance (CE-FDG PET/MR) to discriminate IDC phenotypes.

A practical primer on PI-RADS version 2: a pictorial essay.

Multiparametric magnetic resonance imaging has become an established method for evaluating the prostate for clinically significant prostate adenocarcinoma. Criteria have been developed for categorizing MRI findings, the most frequently used of which is the PI-RADS system. The PI-RADS V2 document provides separate image interpretation and clinical grading sections.
