Rationale And Objectives: To assess the predictive value of MRI-based radiomics of periprostatic fat (PPF) and tumor lesions for predicting Gleason score (GS) upgrading from biopsy to radical prostatectomy (RP) in prostate cancer (PCa).
Methods: A total of 314 patients with pathologically confirmed prostate cancer (PCa) after radical prostatectomy (RP) were included in the study. The patients were randomly assigned to the training cohort (n = 157) and the validating cohort (n = 157) in a 1:1 ratio.
Case report: hibernoma, a rare male breast mass.

Hibernomas are rare, benign neoplasms characterized by the presence of brown adipose tissue. Although these tumors may arise in any region of brown fat, they predominantly occur in the thigh, shoulder, back, and neck. Hibernomas are rarely found in mammary tissue, with a higher prevalence in females than males.

UPMC Department of Radiology, Pittsburgh, PA.
The purpose of this study is to investigate the diagnostic accuracy of a new noninvasive imaging technique, ultrasound-guided attenuation parameter (UGAP), in diagnosing hepatic steatosis. This single-center retrospective study included 81 UGAP studies performed to guide therapy between July 2022 and June 2023 at a large academic medical center. Patients with either liver biopsy or Magnetic resonance-based proton-density fat fraction (MRI-PDFF) within 12 months of US-UGAP imaging, irrespective of order, were included.

Background: Gluteal hypoplasia and ptosis reduction are common concerns among patients seeking optimal body contouring in Peru and other countries. Although silicone implants are a traditional solution, they are not suitable for all patients. Fat grafting has emerged as an alternative, with various techniques aimed at enhancing fat graft viability and patient safety.

Background: This study evaluated the spread of a local anesthetic, using MRI and sensory blockade, after an intertransverse process block (ITPB) at the medial aspect of the retro-superior costotransverse ligament (retro-SCTL) space - the medial retro-SCTL space block.
Methods: Ten healthy volunteers received a single-injection ultrasound-guided medial retro-SCTL space block at the T4-T5 level using a mixture of 10 ml 0.5 % bupivacaine with 0.
