This study reviews the literature on gastric metastases (GM) in terms of diagnosis, treatment, and outcomes. The goal of this study was to provide clinicians with a reliable and beneficial source to understand gastric metastases arising from various primary tumors and to present the growing literature in an easily accessible form. Articles published in English language from implementation of MEDLINE and Cochrane databases until May 2022 were considered for the systematic review.

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).

Virtual non-enhanced dual-energy computed tomography reconstruction: a candidate to replace true non-enhanced computed tomography scans in the setting of suspected liver alveolar echinococcosis.

Purpose: When a suspected hepatic alveolar echinococcosis (AE) lesion is detected on a contrast enhanced computed tomography (CT) scan, an additional triphasic or non-enhanced CT scan is required to determine the presence of calcification and enhancement. As a result, imaging costs and exposure to ionizing radiation will increase. We can create a non-enhanced series from routine contrast-enhanced images using dual-energy CT (DECT) and virtual non-enhanced (VNE) images.

Use of dual energy CT urography in evaluation of urinary stone and complex cyst.

Background: Dual-energy computed tomography scans can provide significant benefits to the urinary system. The aim of this study is to determine the limitations and benefits of using dual energy CT urography in patients with urinary system stones and cysts.

Methods: In the analysis of the images, the virtual noncontrasted images obtained from the combined nephrogenicexcretory phase and the true noncontrasted images were evaluated.

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.

Efficacy of Su Jok Seed Therapy in Migraine: A Randomized Placebo-Controlled Study.

Introduction: Migraine is an important health problem that negatively affects individuals' activities of daily living. The decrease in the quality of life because of migraine increases the need for the development of new pharmacological and nonpharmacological treatment methods for pain management. Limited studies have reported the application of a traditional therapy, such as Su Jok seed therapy, to prevent or minimize migraine.

Evaluation of CSF flow dynamics in patients with schizophrenia using phase-contrast cine MRI.

Patients with schizophrenia show progressive clinical deterioration. Brain abnormalities have been suggested in these patients, including enlargement of the lateral ventricles, increased cerebrospinal fluid (CSF) volume and reductions in the frontal and temporal lobes. CSF flow pathology is a central factor in the development of many neurological disorders, but much less is known about the role of CSF flow dynamics in schizophrenia.

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.

Variation in the radon concentrations and outdoor gamma radiation levels in relation to different geological formations in the thermal regions of Bursa, Turkey.

Spring waters used as spas and their region may contain significant amounts of natural radionuclides. The main sources of exposure are the inhalation of radon and its decay products released from the water and soil and terrestrial gamma-radiation. In order to evaluate the potential risk of thermal regions in Bursa, located in the impact area of the NAF (North Anatolian Fault), radon and thoron concentrations in soil gas, radon concentrations in thermal waters and outdoor gamma radiation levels were measured in thermal regions that have different geological formations.

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.

A (18)F-FDG PET/CT Screening Study of a Hepatocellular Carcinoma Patient with Diffuse (18)F-FDG Uptake into the Portal Vein and its Intrahepatic Branches.

Major vascular invasion is one of the worst prognostic factors of hepatocellular carcinoma (HCC). Fludeoxyglucose F 18 ((18) F-FDG) positron emission tomography/computed tomography (PET/CT) method is succesfully being used in HCC patients for the detection of particularly long-distance metastasis. Major vascular invasion is shown by radiological methods [particularly dynamic CT and/or magnetic resonance imaging (MRI)].
