Background: Magnetic resonance imaging (MRI) findings in asymptomatic patients have been described for hips, knees, ankles, shoulders, and intervertebral disks. No such description exists for the elbow.
Methods: MRI scans of 189 asymptomatic elbows divided into 3 groups by age (group 1, 20-39 years; group 2, 40-59 years; and group 3, ≥60 years) were evaluated for abnormalities within 13 anatomic structures using a novel classification system.
Results: At least 1 variation was found in all elbows. Of the 13 structures, 8 showed an increase in the prevalence and intensity of signal changes with aging, 2 remained the same, and 2 showed a decrease. One anatomic structure showed no variations in any elbow.
Conclusions: Elbow MRI variations may be seen regardless of symptoms. These changes appear to increase in prevalence and intensity with age. Results from this study can be used to help guide the clinician in interpreting MRI findings of the elbow. We hope this study helps provide a contextual background for discussing MRI findings with patients and differentiating age-related variations from true pathology.

Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

Objective: An MRI protocol for germinoma surveillance after complete remission has not been established. Moreover, the standard treatment for recurrent or refractory germinoma has not been determined. In this study, the authors explored the imaging characteristics of recurrent germinoma and discuss their institution's experience with multidisciplinary treatment of this malignancy.

Neoplastic meningitis, also known as leptomeningeal metastases, is a rare clinical entity seen in less than 1%-2% of primary nervous system tumors. Diagnosis of leptomeningeal metastases is difficult and is achieved by cytologic evidence of malignant cells in cerebrospinal fluid, or demonstration of radiologic abnormality. 18F-FDG PET/CT can detect leptomeningeal metastases before anatomical changes.

Purpose: Adaptive radiotherapy accounts for interfractional anatomic changes. We hypothesize that changes in the gross tumor volumes identified during daily scans could be analyzed using delta-radiomics to predict disease progression events. We evaluated whether an auxiliary data set could improve prediction performance.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.
