Congestive hepatopathy: the role of the radiologist in the diagnosis.
lez D Abstract The liver has a complex vascularization and is subjected to a high metabolic demand, making it vulnerable to hemodynamic changes. As a result, several pathologies can develop, one of which is congestive hepatopathy. This disease occurs secondary to various cardiovascular conditions that generate a persistent passive venous congestion in the liver, which in the long term can culminate in fibrosis and cirrhosis, which in turn increases the risk of developing hepatocellular carcinoma. In order to avoid this outcome, early diagnosis is crucial; however, both the clinical presentation and laboratory test...

Hepatocellular carcinoma with macrovascular invasion: multimodality imaging features for the diagnosis.
Abstract Hepatocellular carcinoma (HCC) is frequently associated with macrovascular invasion of the portal vein or hepatic veins in advanced stages. The accurate diagnosis of macrovascular invasion and the differentiation from bland non-tumoral thrombus has significant clinical and management implications, since it narrows the therapeutic options and it represents a mandatory contraindication for liver resection or transplantation. The imaging diagnosis remains particularly challenging since the imaging features of HCC with macrovascular invasion may be subtle, especially in lesions showing infiltrative appearance...

TACE combined with microwave ablation therapy vs. TACE alone for treatment of early- and intermediate-stage hepatocellular carcinomas larger than 5 cm: a meta-analysis.
Abstract There are many therapeutic options for primary hepatocellular carcinoma (HCC), but very limited options for unresectable HCC with a single lesion larger than 5 cm (Barcelona Clinic Liver Cancer [BCLC] stage A) or with 2-3 nodules beyond 5 cm (BCLC stage B). Transcatheter arterial chemoembolization (TACE) is considered the first-line treatment for these patients, and combination therapy has also been tried. However, the efficacy of microwave ablation (MWA) combined with TACE in the treatment of the above tumors remains to be further confirmed. Therefore, this meta-analysis aimed to compare the efficacy of ...

Visual PET/CT scoring of mesenteric fdg uptake to differentiate between tuberculous peritonitis and peritoneal carcinomatosis.
Abstract PURPOSE: We aimed to differentiate tuberculous peritonitis (TBP) from peritoneal carcinomatosis (PC) using a visual positron-emission tomography/computed tomography (PET/CT) scoring system based on mesenteric fluorodeoxyglucose (FDG) uptake. METHODS: PET/CT scans from 31 patients with TBP and 92 patients with PC were retrospectively reviewed. A visual PET/CT scoring system for mesenteric FDG uptake was used according to the following characteristics: FDG uptake intensity (low = 0, moderate = 1, high = 2), FDG uptake deposits (uniform = 0, irregular = 1, ascitic = 2), FDG uptake focality (diffuse = 0,...

Is bone marrow edema syndrome a precursor of hip or knee osteonecrosis? Results of 49 patients and review of the literature.
CONCLUSION: Our study shows that subchondral lines and spots found in patients with BMES do not develop into AVN. Subchondral lines, which resemble subchondral insufficiency fractures, are associated with BMES. Subchondral focal T1-hypointense zones do not represent AVN; most probably these areas represent reparative processes within the subchondral bone, where tensile and shear force overload is present due to altered biomechanics.

Percutaneous endobiliary forceps biopsy of biliary strictures for histopathological examination.
CONCLUSION: Percutaneous transhepatic biliary drainage (PTBD)-based forceps biopsy via the transhepatic drainage tract in patients with biliary obstruction of unknown origin is a technically feasible and safe technique with good diagnostic value rates. The procedure should be considered in patients not suitable for endoscopic strategies with indication for establishment of PTBD.

Liver stiffness value obtained by point shear wave elastography is significantly related with atrial septal defect size.
H, Çakır Pekoz B, Koç M Abstract PURPOSE: The increase in volume and pressure in the right atrium (RA) and right ventricle (RV) has been shown to increase the liver stiffness (LS). In the literature, there is no information about the changes in LS value in patients with atrial septal defect (ASD). The aim of our study was to investigate the change of LS values obtained by point shear-wave elastography (pSWE) in patients with ASD and the clinical utility of pSWE for this disease. METHODS: This cross-sectional study included 66 patients with ostium secundum ASD: 21 patients with no indication fo...

Association between tears of the posterior root of the medial meniscus and far posterior femoral condyle osteoarthritis.
Abstract PURPOSE: We aimed to evaluate whether tears of the posterior horn of the medial meniscus root ligament (PHMM RL) are associated with osteoarthritis of the far posterior femoral condyles (FPFC). METHODS: Retrospective review of 1158 patients who underwent arthroscopy identified 49 patients with confirmed tears of the medial meniscus posterior root ligament attachment. Preoperative magnetic resonance imaging (MRI) studies were reviewed to identify advanced osteoarthritis involving the medial and lateral FPFC. Control patients (n=48) had no meniscal tears confirmed by arthroscopy. Cases and controls wer...
