Pediatric Hepatoblastoma After Neoadjuvant Chemotherapy: Diagnostic Performance of MR in Staging POSTTEXT and Vascular Involvement.

Background: The assessment of resectability after neoadjuvant chemotherapy of hepatoblastoma is dependent on Post-Treatment EXTENT of Disease (POSTTEXT) staging and its annotation factors P (portal venous involvement) and V (hepatic venous/inferior vena cava [IVC] involvement), but MR performance in assessing them remains unclear.

Purpose: To assess the diagnostic performance of contrast-enhanced MR imaging for preoperative POSTTEXT staging and diagnosing vascular involvement in terms of annotation factors P and V in pediatric hepatoblastoma following neoadjuvant chemotherapy.

Study Type: Retrospective.

Creeping fat in patients with ileo-colonic Crohn's disease correlates with disease activity and severity of inflammation: A preliminary study using energy spectral computed tomography.

Objective: To investigate the relationship between creeping fat and inflammatory activity as well as the prognosis of ileo-colonic Crohn's disease (CD), based on a quantitative analysis of energy spectral computed tomography (CT).

Methods: A total of 40 patients with CD and 40 with other gastrointestinal diseases who underwent an energy spectral CT scanning between March 2014 and March 2015 were retrospectively enrolled. The endoscopic severity of CD was evaluated by the simple endoscopic score for Crohn's disease (SES-CD).

Optimal b value of diffusion-weighted imaging on a 3.0T magnetic resonance scanner in Crohn's disease.

Aim: To determine the optimal b value of diffusion-weighted imaging for detecting active inflammation in Crohn's disease.

Methods: Thirty-one patients clinically diagnosed with active Crohn's disease were referred for magnetic resonance examination. All patients were scanned on a 3.

T staging of rectal cancer: accuracy of diffusion-weighted imaging compared with T2-weighted imaging on 3.0 tesla MRI.

Objective: To evaluate the performance of diffusion-weighted imaging (DWI) in the T staging of primary rectal cancer compared with T2-weighted (T2W) fast spin-echo imaging using 3.0 tesla magnetic resonance imaging (MRI).

Methods: In total, 46 consecutive patients with rectal cancer who underwent MRI examination before surgery were included in the study.

[The effect of anticoagulant thrombolytic therapy on acute deep venous thrombosis prognosis].

Objective: To explore the effect of anticoagulant thrombolytic therapy on acute deep venous thrombosis (DVT) and the incidence and severity of post-thrombotic syndrome (PTS).

Method: A total of 111 patients (113 limbs) with central or mixed types of deep venous thrombosis admitted from March 2003 to November 2008 were analyzed. The patients were divided into 3 groups by different therapies: anticoagulant group (41 limbs), thrombolysis group (27 limbs), and catheter-directed thrombolysis group (45 limbs).
