PURPOSE Diagnosis of partial rotator cuff tears and tendonopathy using conventional MRI has proven variable. Quantitative T2 mapping may have application for assessing rotator cuff health. In order to evaluate the usefulness of T2 mapping for the rotator cuff, methods must be refined for mapping the supraspinatus tendon, and normative T2 values must first(More)
PURPOSE To determine the efficacy and safety of percutaneous transluminal angioplasty (PTA) of the visceral arteries. PATIENTS AND METHODS We retrospectively evaluated the results of PTA performed in 20 visceral arteries in 19 patients (10 men, nine women; mean age, 63 years). Eleven patients had symptoms characteristic of mesenteric ischemia, four had(More)
OBJECTIVE A standardized definition of normative T2 values across the articular surface of the hip must be defined in order to fully understand T2 values for detecting early degeneration. Therefore, in this article, we seek to lay foundational methodology for reproducible quantitative evaluation of hip cartilage damage using T2 mapping to determine the(More)
In order for T2 mapping to become more clinically applicable, reproducible subregions and standardized T2 parameters must be defined. This study sought to: (1) define clinically relevant subregions of knee cartilage using bone landmarks identifiable on both MR images and during arthroscopy and (2) determine healthy T2 values and T2 texture parameters within(More)
Positron emission tomography (PET) use is increasing; however, optimal utilization in gynecologic oncology remains unclear. PET is expensive, has limited anatomic detail, and it may be difficult to differentiate benign ovarian lesions from malignant lesions when PET is used. A 43-year-old female volunteer's PET scan revealed increased uptake in the left(More)
PURPOSE To describe T2 mapping values in arthroscopically determined International Cartilage Repair Society (ICRS) grades in damaged and healthy-appearing articular cartilage waste specimens from arthroscopic femoroacetabular impingement (FAI) treatment. Furthermore, we sought to compare ICRS grades of the specimens with biochemical, immunohistochemistry(More)
