Can T1W and T2W Dixon Sequences Replace the Standard MRI Protocol in Diagnosing Sacroiliitis?

This study aims to assess the performances of T1‑weighted (T1W) and T2‑weighted (T2W) Dixon sequences as replacements for the standard magnetic resonance imaging (MRI) protocol for diagnosing active and chronic sacroiliitis. This single‑centre, prospective study included 107 patients who underwent 3 Tesla MRIs. The patients with inflammatory low‑back pain (aged 18-50 years) were included.

Comparison of liver resection and living donor liver transplantation in patients with hepatocellular carcinoma within Milan criteria and well-preserved liver function.

Background And Aim: Liver resection (LR) and liver transplantation (LT) are curative treatments for hepatocellular carcinoma (HCC). The main purpose of this study was to compare the survival of LR and LDLT in patients with HCC within the Milan criteria.

Materials And Methods: The results of the LR (n=67) and LDLT (n=391) groups were compared for overall survival (OS) and disease-free survival (DFS).

Incidental Hepatocellular Carcinoma after Liver Transplantation: Clinicopathologic Features and Prognosis.

Background: The prognostic impact and clinicopathologic features of incidental hepatocellular carcinoma (iHCC) detected in explanted livers of patients undergoing liver transplantation (LT) has been a controversial issue in previous studies when compared with patients who are diagnosed with hepatocellular carcinoma (pdHCC) before LT. We aimed to review and compare these patient groups in a high-volume LT center. Methods: The present study involves a retrospective analysis of 406 HCC patients who received LT between January 2002 and April 2022.

Cerebrospinal Fluid Dynamics in Patients with Multiple Sclerosis: The Role of Phase-Contrast MRI in the Differential Diagnosis of Active and Chronic Disease.

Objective: Multiple sclerosis (MS) is an inflammatory disease characterized by demyelinating plaques in the white matter. Chronic cerebrospinal venous insufficiency (CCSVI) has been proposed as a new hypothesis for the etiopathogenesis of MS disease. MS-CCSVI includes a significant decrease of cerebrospinal fluid (CSF) flow through the cerebral aqueduct secondary to an impaired venous outflow from the central nervous system.

The right vertebral artery originating from the right occipital artery and the absence of the transverse foramen: a rare anatomical variation.

Variations in the origin of the vertebral artery (VA) is a congenital anomaly that occurs during embryological development. Multiple variations related to VA origin have been reported in the literature. Abnormal VA origin is usually determined as incidental findings during angiographic or postmortem anatomical studies.

Reconstruction of Anomalous Portal Venous Branching in Right Lobe Living Donor Liver Transplantation: Malatya Approach.

Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit.

Preoperative evaluation of liver volume in living donor liver transplantation.

Objective: The aim of the present study was to retrospectively evaluate the difference between the preoperative estimated volume and the actual intraoperative graft volume determined in donor right hepatectomies and to evaluate the possible effect of age, gender, and body mass index on the difference.

Methods: A total of 225 donor hepatectomies performed at the center between 2016 and 2017 were evaluated for the study. Left hepatectomies and left lateral segmentectomies were excluded from the analysis.

The evaluation of non-ischemic dilated cardiomyopathy with T1 mapping and ECV methods using 3T cardiac MRI.

Purpose: The aim of this study was to examine the correlation between ventricular function and the extracellular volume fraction (ECV) in patients with non-ischemic dilated cardiomyopathy (NIDCM) using 3.0 T magnetic resonance imaging (MRI). We also hypothesized that native T1 and ECV values would be increased in patients with NIDCM, independent of the left ventricular ejection fraction (LVEF).

Langerhans Cell Histiocytosis with Atypical Intervertebral Disc and Sacroiliac Joint Involvement Mimicking Osteoarticular Tuberculosis in an Adult.

Background: Langerhans cell histiocytosis (LCH), typically found in children, is a rare single or multisystem disorder with a wide range of clinical and radiological manifestations. Unusual presentations of LCH are occasionally encountered and it may be difficult to distinguish LCH from an infection or a benign or malignant tumor.

Results: A 35-year-old female presented with pain in her back and left buttock, malaise, and weight loss, with a duration of several months.

Sudden-onset paraplegia during pregnancy caused by haemorrhage in a spinal cord haemangioblastoma: A case report.

Spinal cord haemangioblastomas are rare central nervous systems tumours, and haemorrhage.It is an uncommon occurance. We report a 28-year-old pregnant patient who presented with paraplegia due to acute haemorrhage of a spinal haemangioblastoma.

Unusual Symptomatic Multipartite Patella Associated with Quadriceps Fat Pad Edema.

Partite patella is a known cause of anterior knee pain, especially in adolescents and young males, although most patients are asymptomatic. Symptomatic partite patella is usually revealed on magnetic resonance imaging (MRI) as bone marrow edema within the opposing bone fragments. We present a case of unusual bilateral symptomatic multipartite patella in an adult who presented with quadriceps fat pad edema and mass effect as well as slightly edematous signal changes within the bone fragments on MRI.

Congenital Agenesis of Right Internal Carotid Artery: A Report of Two Cases.

Congenital unilateral agenesis of the internal carotid artery (ICA) is a rare anomaly. Due to proper sufficient collateral circulation via the circle of Willis most cases are asymptomatic, but patients can also present with ischemic or hemorrhagic cerebrovascular insults. The absence of the bony carotid canal is essential to differentiate this anomaly from chronic ICA occlusion.

Assessment of myocardial changes in athletes with native T1 mapping and cardiac functional evaluation using 3 T MRI.

Intensive physical exercise leads to increases in left ventricular muscle mass and wall thickness. Cardiac magnetic resonance imaging allows the assessment of functional and morphological changes in an athlete's heart. In addition, a native T1 mapping technique has been suggested as a non-contrast method to detect myocardial fibrosis.

Diffusion-weighted imaging (DWI) of the liver in assessing chronic liver disease: effects of the presence and the degree of ascites on ADC values.

Purpose: The aim of this study was to determine the correlation between the liver and spleen apparent diffusion coefficient (ADC) values of patients with chronic liver disease and the presence and the degree of ascites.

Materials And Method: In this retrospective study, we assessed 107 patients with chronic liver disease and 39 control subjects who underwent upper abdominal MR imaging including echo-planar diffusion-weighted imaging (DWI). Among the 107 cirrhotic patients, 56 were classified as group 1, 25 as group 2, and 26 as group 3 according to the absence, the presence of minimal, and the presence of massive ascites, respectively.

Background: To evaluate the relationship of the intercondylar notch width with unilateral and bilateral ACL injury by using MR images.

Material And Methods: The intercondylar notch width index was measured on the MR images of 18 patients with a bilateral ACL injury, 38 patients with a unilateral ACL injury and 53 healthy subjects with a normal ACL and the results of all groups were compared with each other.

Results: The mean NWI values were 0,227 (±0.

Image-guided percutaneous bone biopsy with a simulated van sonnenberg removable hub system.

Objective: To retrospectively examine the success and complication rates associated with image-guided percutaneous bone biopsy with a simulated Van Sonnenberg removable hub system.

Materials And Methods: During a 3.5-year period, 27 bone lesions at different anatomic locations with an indication for biopsy based on plain film, computed tomography (CT) and/or magnetic resonance imaging (MRI) findings were determined, and a total of 28 image-guided (fluoroscopy or CT) percutaneous biopsies were performed using a simulated Van Sonnenberg -removable hub system.

No mortality or pancreatic fistula after full-thickness suture pancreaticogastrostomy in 39 patients who underwent pancreaticoduodenectomy.

Pancreaticoduodenectomy is considered the standard operation for periampullary tumors. Despite major advances in pancreatic surgery, pancreatic fistula is still an important cause of morbidity and mortality after pancreaticoduodenectomy. Meticulous surgical technique and proper reconstruction of the pancreas are essential to prevent pancreatic fistula.

Adventitious bursitis overlying an osteochondroma of the humerus facing the thoracic wall.

One of the complications of osteochondromas is the development of a bursa over the cartilaginous cap. We report a 15-year-old boy with a rapidly expanded adventitious bursitis overlying an osteochondroma of the humerus facing the thoracic wall, a location not previously reported for such bursa formation. Magnetic resonance imaging readily showed adventitious bursitis overlying the osteochondroma, thereby dispelling concerns for malignant transformation.

Synovial chondromatosis of the temporomandibular joint: radiologic and histopathologic findings.

Synovial chondromatosis is a formation of multiple intrasynovial nodules resembling osteochondromas, resulting from proliferative changes in the synovial linings of joints; as the disorder progresses, nodules increasingly withdraw from the intrasynovial areas for the joint cavities. This is a relatively unusual case that can arise at unilateral large joints, such as knee, hip, and elbow, with the temporomandibular joint being the rarest one of them. Early recognition of the signs and symptoms with resultant accurate diagnosis, as well as proper surgical treatment, offers patients the best hope of recovery and improved quality of life.
