The reliability of virtual non-contrast reconstructions of photon-counting detector CT scans in assessing abdominal organs.

Background: Spectral imaging of photon-counting detector CT (PCD-CT) scanners allows for generating virtual non-contrast (VNC) reconstruction. By analyzing 12 abdominal organs, we aimed to test the reliability of VNC reconstructions in preserving HU values compared to real unenhanced CT images.

Methods: Our study included 34 patients with pancreatic cystic neoplasm (PCN).

Impact of a Targeted Project for Shortening of Imaging Diagnostic Waiting Time in Patients with Suspected Oncological Diseases in Hungary.

Medical imaging is a key element in the clinical workup of patients with suspected oncological disease. In Hungary, due to the high number of patients, waiting lists for Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) were created some years ago. The Municipality of Budapest and Semmelweis University signed a cooperation agreement with an extra budget in 2020 (HBP: Healthy Budapest Program) to reduce the waiting lists for these patients.

Microvascular flow imaging to differentiate focal hepatic lesions: the spoke-wheel pattern as a specific sign of focal nodular hyperplasia.

Microvascular flow imaging (MVFI) is an advanced Doppler ultrasound technique designed to detect slow-velocity blood flow in small-caliber microvessels. This technique is capable of realtime, highly detailed visualization of tumor vessels without using a contrast agent. MVFI has been recently applied for the characterization of focal liver lesions and has revealed typical vascularity distributions in multiple types thereof.

Polymyositis and rhabdomyolysis caused by hepatocellular carcinoma - Case report and literature review.

Introduction: Rhabdomyolysis is a syndrome characterized by a rapid necrosis of muscle fibers and the release of muscle-derived metabolic products into the circulatory system. A rare cause of rhabdomyolysis is paraneoplastic polymyositis.

Case Presentation: A 67-year-old man was diagnosed with paraneoplastic polymyositis and rhabdomyolysis caused by hepatocellular carcinoma (HCC).

[Decreasing morbidity after Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) with technical modification and patient selection].

Resecability of liver tumors is exclusively depending on the future liver remnant (FLR). The remnant can be hypertrophised using portal vein occlusion techniques. The latest hypertrophising method is Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS), which provides the most significant induced hypertrophy in the shortest time.

Optimal line of hepatotomy for left lateral living donor liver transplantation according to the anatomical variations of left hepatic duct system.

Multiple duct anastomoses during LLS transplantation increase the incidence of biliary complications. The optimal plane of hepatotomy that results in the least number of bile ducts at the surface was investigated according to LHD variations. Ducts of 30 human livers were injected with resin and LHD branching on 3D-CT reconstructions were analyzed.

The utility of the combination of the corrosion cast method and post mortem MSCT scans.

A careful post-mortem investigation is needed to determine the cause of death of patients bearing coronary stents and to describe complications of stent implantation. The main purpose of this study was to combine post mortem methods of CT angiography and corrosion cast preparation for the visualization of coronary stenoses, coronary stents, instent restenosis, and stent occlusion. Injection-corrosion method was combined with post-mortem MSCT angiography to characterize the pathomorphological changes after stent implantation in 6 male cadaver hearts.

PEG fixation of an upside-down stomach using a flexible endoscope: case report and review of the literature.

Introduction: Upside-down stomach usually is asymptomatic in adults, but sometimes it can cause regurgitation, vomiting, and weight loss. This condition has an incidence increasing with age thus increasing the risk of surgical intervention.

Case Report: A 90-year-old man was admitted with dysphagia, postprandial regurgitation, and an 18 kg weight loss in the past year.

[ALPPS (Associated Liver Partition and Portal vein ligation for Staged hepatectomy) -- faster and greater growth of liver].

75 years old female patient was referred with large, multifocal colorectal liver metastasis. Prior to this consultation she received chemotherapies of various protocols and series. Liver metastasis, however, increased at about 3 times of the original size during the 5 months of the oncological treatment.
