Introduction: Whole-body MRI (WB-MRI) is increasingly used in clinical practice for detection of malignant bone disease. A high relative contrast ratio (RCR) of malignant bone lesions compared with normal bone can improve disease detection in breast, prostate and myeloma malignancies. However, the RCR of malignant bone lesions on T1w, DWI and relative Fat Fraction (rFF) maps derived from Dixon T1w have not been compared.

An aberrant right subclavian artery (ARSA) is a rare vascular anomaly accompanied by nonrecurrent inferior laryngeal nerve (NRILN). Here, we described the cervical-first approach in thoracoscopic esophagectomy for an esophageal cancer patient with ARSA using the intraoperative nerve monitoring (IONM) system. First, a left cervical procedure proceeded to expose the left vagus nerve to attach the APS electrode of the IONM system, and the left cervical paraesophageal lymph nodes was dissected separately.

Background: Appropriate immobilization setup for postmastectomy radiotherapy may help to improve tumor control and to reduce radiation-related toxicities. This study aims at retrospectively evaluate the outcome and toxicities of postmastectomy radiotherapy (PMRT) with a novel integral cervicothoracic thermoplastic mask strategy.
Methods: Breast cancer patients were treated with modified radical mastectomy and PMRT.
Management of Cervical Spine Metastasis from Renal Cell Carcinoma: A Rare Case Report with an Overview.

Introduction: Renal cell carcinoma (RCC) accounts for 2-3% of adult malignant tumors, often metastasizing to bones, especially the spine. Spinal metastasis has a poor prognosis, but solitary spinal tumors have better outcomes with targeted chemotherapy, radiotherapy, and newer surgical approaches. Due to RCC's high vascularity and resistance to treatments, en bloc vertebrectomy with anterior and posterior fixation is the gold standard for solitary lesions.

Objective: FAPI-PET/CT exhibits high tumor uptake and low background accumulation, enabling high-sensitivity tumor detection. We compared the diagnostic performance of Ga-FAPI-46 PET/CT plus contrast-enhanced CT (CE-CT), F-FDG PET/CT plus CE-CT, and standalone CE-CT in patients with various malignancies.
Methods: 232 patients underwent Ga-FAPI-46 PET/CT,F-FDG PET/CT, and CE-CT each within 4 weeks.
