Article Synopsis
- The study aimed to determine if the time required for radiopharmaceutical uptake in bone scintigraphy could be shortened for SPECT imaging of the jawbone, focusing on patients with osteonecrosis.
- A total of 33 patients were observed, with SPECT scans conducted at both 2 and 3 hours after injection of technetium-99m, assessing the standardized uptake values (SUVmax) for parietal bones and jawbone lesions.
- The findings indicated no significant clinical difference in SUVmax values between the two time points, suggesting that the uptake time can be safely reduced to 2 hours without impacting the imaging results.
Article Synopsis
- - A rare case of colon cancer was reported where the middle colic artery (MCA) arose from the splenic artery (SA) instead of the usual location, the superior mesenteric artery (SMA).
- - A woman underwent laparoscopic surgery for transverse colon cancer, where 3D-CT angiography helped identify the unusual MCA before operation, allowing for safer dissection of lymph nodes around the SMA.
- - This case highlights the importance of advanced imaging techniques to prevent surgical complications and is notable as the first documented instance of laparoscopic colectomy involving an MCA originating from the SA.
Background: The aim of the study was to investigate a prevalence of sarcopenia in patients with gynecological cancer in accordance with current diagnostic criteria of sarcopenia.
Methods: A series of 513 patients with gynecological cancer who were intended to newly receive initial or salvage treatment were recruited in a prospective study. Eligible patients were examined with dual energy X-ray absorptiometry and underwent handgrip strength test and the Short Physical Performance Battery before treatment.
Background: The current study investigated an optimal method for using CT scan in detection of low skeletal muscle mass quantity (SMQ).
Methods: In total, 82 consecutive patients with gynecological cancers were examined using computed tomography (CT) and dual-energy X-ray absorptiometry (DEXA) before treatment. Low SMQ was defined as a DEXA-based skeletal muscle mass index (SMI) of <5.
Objective: The aim of this study was to find a clinical marker for identifying refractory cancer cachexia.
Methods: We analyzed computed tomography imaging data, which included the third lumbar vertebra, from 94 patients who died of uterine cervix or corpus malignancy. The time between the date of examination and date of death was the most important attribute for this study, and the computed tomography images were classified into >3 months before death and ≤ 3 months before death.
Article Synopsis
- The study assessed the effectiveness of measuring psoas muscle mass as a way to identify low skeletal muscle mass in 82 patients with gynecological cancers using CT scans and dual-energy X-ray absorptiometry.
- Results showed that 28% of patients had low skeletal muscle mass, with the psoas muscle mass index being significantly related but not strongly correlated with the skeletal muscle mass index.
- The findings suggest that while psoas muscle mass can be an indicator of low skeletal muscle mass, it should not be the primary method used for detection, as its diagnostic agreement is only moderate.
