Lumbosacral transitional vertebrae are associated with lumbar degeneration: retrospective evaluation of 3855 consecutive abdominal CT scans
AbstractObjectivesTo assess the prevalence of lumbosacral transitional vertebra (LSTV) and associated spinal degenerative changes on abdominal CT scans in Caucasian population.Material and methodsA total of 3855 abdominal CT scans of the year 2017 from a single hospital were retrospectively assessed for LSTV, disc degeneration (DD), and facet joint degeneration (FD). An age- and sex-matched 150-subject control group without LSTV was picked at random. Multivariable logistic regression was used for the analysis.ResultsLSTV was found in 1101 (29%) scans: Castellvi type I in 68%, type II in 16%, type III in 13%, and type IV in 3% of scans. Age- and sex-adjusted prevalence of DD was significantly higher in Castellvi type II and III groups at multiple lumbar levels, and in IV group at L4/5 than in control group (p
We presented a rare case of primary pleural squamous cell carcinoma (SCC) on fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). It manifested as multiple pleural nodules with moderate 18F-FDG uptake and massive pleural effusion on PET/CT. The pathology result supported the primary squamous cell carcinoma. Our case highlighted the SCC should be included as differential diagnosis of the multiple pleural lesions and other differential diagnosis consisted of mesothelioma, solitary fibrous tumor, metastases.

We present a case of a 79 year old patient with a medical history of unilateral nerve-sparing radical prostatectomy due to a pT3aN0 (Gleason score 7) prostate carcinoma. Because of slightly elevated prostate specific antigen (PSA) level (0.35ng/dL), a fluorine-18-prostate specific membrane antigen (18F-PSMA)-1007 positron emission tomography/computed tomography (PET/CT) scan was performed, showing no signs of malignant recurrence. However, a moderately PSMA-avid nodular lesion was observed in the left occipital region with homogeneous contrast enhancement, suggestive for a meningioma, which was confirmed on magnetic resona...
Authors: Sachpekidis C, Exadaktylou P, Katsampoukas D, Moralidis E, Arsos G Abstract Peritoneal lymphomatosis, defined as the disseminated intraperitoneal lymphomatous infiltration, is a rare presentation usually of non-Hodgkin lymphoma and is associated with aggressive histological subtypes of the malignancy. Recently, the term "peritoneal super scan" has been introduced in positron emission tomography/computed tomography (PET/CT) in a patient with Burkitt lymphoma to describe hypermetabolic lymphomatous involvement of the entire peritoneum, leading to suppression of tracer uptake in organs with otherwis...
Authors: Altini C, Lavelli V, Ruta R, Ferrari C, Nappi AG, Pisani A, Sardaro A, Rubini G Abstract Nuclear Medicine multimodality imaging, such as positron emission tomography/computed tomography PET/CT, refers to metabolic tissue characteristics integrated with anatomical details. Fluorine-18-fluorodeoxyglucose (18F-FDG) is the most diffuse radiopharmaceutical and its application is spreading beyond the area of oncology. The causes of high 18F-FDG uptake that were once considered false positives have been identified and the new knowledge about them led to non-cancerous pathologies that can be studied by 18F-FDG PET...
CONCLUSION: Carbon-11-choline PET was found have a greater correlation with Gleason score than DWI and is considered to be more useful to predict a higher score in patients with prostate cancer. Fluorine-18-FDG PET was limited because of low sensitivity. PMID: 32222730 [PubMed - as supplied by publisher]
We previously developed a post LVAD mortality prediction model using multicenter data incorporating pectoralis muscle mass and tissue attenuation obtained on preoperative CT scans. The purpose of this analysis was to evaluate the performance of this model in a prospective cohort including the most contemporary LVADs.
Cardiac cachexia with associated sarcopenia and frailty has been associated with adverse outcomes after placement of a durable left ventricular assist device (LVAD). The purpose of this study is to examine whether the pectoralis muscle index (PMI) measured from preoperative CT scans of the chest will predict outcomes after LVAD implantation.
Hepatic cirrhosis is a potential severe complication of chronic heart failure and has major implications on treatment options. In general, patients with cirrhosis are considered ineligible for isolated cardiac transplantation. Therefore, proper diagnosis of cirrhosis is paramount. The aim of this retrospective study is to explore the diagnostic value of abdominal ultrasound, hepatosplenic scan and abdominal computed tomography scan (CT scan) for liver disease secondary to advanced heart failure.
Donor shortage remains a major obstacle associated with considerable mortality in patients waiting for lung transplantation (LTx). Objective donor lung assessment is crucial to obtain sufficient grafts of acceptable quality. We hypothesized that out of body chest CT may be an innovative way to assess grafts prior to LTx. Therefore, this study prospectively investigated the value of CT scan of donor lungs prior to LTx.
Pectoralis muscle mass and tissue attenuation obtained on preoperative CT scans are powerful predictors of mortality after LVAD implantation. Gastrointestinal (GI) bleeding remains a common problem on mechanical support. It is unknown whether these skeletal muscle measures, which correlate with frailty and tissue quality, are associated with the development of recurrent GI bleeding.
