Para-articular and intra-articular soft tissue lesions: Radiologic-pathologic correlation.

Articular masses comprise various disease entities including benign or malignant proliferative processes and other non-neoplastic processes such as infection, deposition diseases, vascular malformations, and other lesions. Many diseases that lead to intra-articular or para-articular masses have distinct imaging features, particularly on MRI. Radiologists can localize masses to the joint space by knowing the articular anatomy and can reach a suggested diagnosis by looking at precise imaging findings.

Factors affecting radiation dose, radiation exposure time and procedural time in arterial embolization for active hemorrhage.

Purpose: To evaluate patient and procedure-related factors contributing to the radiation dose, cumulative fluoroscopy time (CFT), and procedural time (PT) of Arterial Embolization (AE) for suspected active bleeding.

Methods: Data on patients who underwent AE for suspected bleeding was retrospectively gathered between January 2019 and April 2022. Data collected included the dependent variables consisting of dose-area product (DAP), CFT, PT, and independent variables consisting of demographic, bleeding-specific, and procedure-specific parameters.

Does delayed phase imaging in CT angiography provide additional information in patients with suspected active bleeding?

Purpose: We hypothesize that delayed phase imaging does not provide additional diagnostic information in patients who undergo multi-phasic CTA for suspected active bleeding.

Methods: Data on patients who underwent multiphasic CTA (pre-contrast, arterial, porto-venous, and delayed phases) for suspected acute bleed were retrospectively collected between January 2019 and November 2021. CTA images were reviewed by a general radiologist, an interventional radiologist, and a body imaging radiologist independently.

Massive spinal epidural infantile hemangioma, image findings, and treatment: a case report and review of literature.

Spinal involvement of infantile hemangiomas is rare with the predilection to involve the epidural space. A proper diagnosis might be challenging due to the atypical location and variable/inconsistent use of the International Society for the Study of Vascular Anomalies (ISSVA) classification by radiologists, pathologists, and clinicians. A proper diagnosis of epidural infantile hemangioma is key due to the different aggressiveness of the treatment options with inconstant literature regarding the best available treatment.

The effect of macrocyclic ionic and non-ionic gadolinium agents on neuronal injury and myelin loss in the spinal cords of rats with and without diabetes mellitus.

Background: The effect of gadolinium-based contrast agents (GBCA) on the spinal cord is not established, especially in patients with diabetes mellitus.

Purpose: To investigate neuronal and myelin loss in the spinal cord when employing macrocyclic ionic Gadoterate Meglumine (Gd-DOTA) and non-ionic Gadobuterol (Gd-BT-DO3A) GBCA in rats with and without diabetes mellitus.

Materials And Methods: This study was performed between November 2018 and February 2020.
