Long-term follow-up of transjugular intrahepatic portosystemic shunt (TIPS) with stent-graft.
CONCLUSION: The clinical success rate was high. The choice of the maximum initial limit of portosystemic gradient and the diameter of the post-TIPS shunt, together with the number of shunt reductions, are important to be able to compare results between publications. In our study, the patency rates did not decrease after 6 years; hence, long-term follow-up of these patients may not be necessary.

Avoiding peripheral nerve injury in arterial interventions.
Abstract Although peripheral nerve injuries secondary to angiography and endovascular interventions are uncommon and usually are not permanent, they can result in significant functional impairment. Most arteries used in access for angiography and endovascular therapies lie in close proximity to a nerve. The nerve may be injured by needle puncture, or by compression from hematoma, pseudoaneurysm, hemostasis devices, or by manual compression with incidence in literature ranging from as low as 0.04% for femoral access in a large retrospective study to 9% for brachial and axillary access. Given the increasing frequenc...

The interaction between irreversible electroporation therapy (IRE) and embolization material using a validated vegetal model: an experimental study.
CONCLUSION: The ablation zone arced in the presence of surgical clips at the edge or outside the ablation margins; therefore, nearby critical structures may be susceptible to the effects of IRE. Furthermore, there was no physical degradation of the embolic agents or surgical clips, and this may have importance when considering IRE ablation of previously embolized lesions in vivo.

Diffusion-weighted imaging of placenta in intrauterine growth restriction with worsening Doppler US findings.
CONCLUSION: The diagnostic estimation of placental ADC values to predict the severity of IUGR is comparable to that of umbilical artery PI. Considering that at the very early onset of IUGR, placental diffusion diminishes, ADC as a marker for IUGR in lieu of umbilical artery PI has the potential to determine the threshold for decreased placental diffusion. Therefore, DWI should be added to routine fetal MRI to show diffusion changes in placenta.

Multiparametric MRI in rectal cancer.
alık E Abstract MRI has a pivotal role in both pretreatment staging and posttreatment evaluation of rectal cancer. The accuracy of MRI in pretreatment staging is higher compared with posttreatment evaluation. This occurs due to similar signal intensities of tumoral and posttreatment fibrotic, necrotic, and inflamed tissue. This limitation occurs with conventional MRI of the rectum with morphologic sequences. There is a need towards increasing the accuracy of MRI, especially for posttreatment evaluation. The term multiparametric MRI implies addition of functional sequences, namely, diffusion and perfusion to the r...

Immunoglobulin G4-related disease complicated with vascular lesions: CT findings in 21 patients.
Abstract PURPOSE: We aimed to analyze multislice computed tomography (MSCT) imaging features of vasculitis in immunoglobulin G4-related disease (IgG4-RD). METHODS: In this retrospective study, we diagnosed 21 definite or possible IgG4-RD patients (71.4% male; mean age, 52.1±4.5 years) with vasculitis by MSCT and pathologic examination. The clinical background, laboratory analysis, pathologic results, CT images, and response to therapy were assessed and analyzed. RESULTS: Under enhanced MSCT, 50 vasculitic lesions were identified and were divided into five types (types A-E) according to the CT find...

Vascular imaging findings with high-pitch low-dose dual-source CT in atypical Kawasaki disease.
CONCLUSION: Our results suggest that high-pitch low-dose dual-source CT can detect all types of aneurysms, stenosis and occlusions of vessels in patients with AKD who were not previously diagnosed. This useful, easy, robust and fast technique may be preferred to diagnose AKD.

Long-term balloon indwelling technique for the treatment of single benign biliary stricture.
Abstract We aimed to evaluate the feasibility and safety of long-term balloon indwelling technique for the treatment of single benign biliary stricture. Five patients with single benign biliary stricture were included from December 2014 to November 2016. The patients were three men and two women with a mean age of 50 years (range, 30-65 years). A balloon catheter was inserted into the drainage catheter and emerged through the side hole of the catheter so that the balloon and drainage catheters could be placed together at the stricture site. Follow-up fluoroscopic examination was performed at least once every 2 wee...

MRI findings in patients with acute coronary syndrome and unobstructed coronary arteries.
Abstract PURPOSE: The underlying diagnosis in patients with acute coronary syndrome (ACS) and unobstructed coronary arteries remains a diagnostic challenge. We analyzed the value of magnetic resonance imaging (MRI) in this clinical setting. METHODS: A total of 213 patients with ACS and unobstructed coronary arteries underwent MRI within a median of 2 days after initial presentation. Clinical, laboratory, and MRI data were analyzed. A consensus diagnosis was established for each case by an independent panel after reviewing the individual clinical, laboratory, and MRI data. Standardized interviews to determine ...

Thoracic manifestations of adult T-cell leukemia/lymphoma on chest CT: difference between clinical subtypes.
CONCLUSION: On thoracic CT, enlarged lymph nodes and various lung and airway abnormalities, such as ground-glass attenuation and bronchial wall thickening, were observed in ATL patients, particularly those with aggressive ATL. Bronchiectasis was similarly found in patients with indolent ATL and aggressive ATL.

Focal hypersteatosis: a pseudolesion in patients with liver steatosis.
CONCLUSION: Focal hypersteatosis is a pseudolesion that can be observed in patients with liver steatosis. It appears hypodense on CT and mostly isoechoic on US relative to fatty liver. It may mimic metastasis in cancer patients with steatosis, due to nodular shape and atypical location. MRI should be used for correct diagnosis in patients with equivocal findings on CT to avoid biopsy.
