Measuring the apparent diffusion coefficient in primary rectal tumors: is there a benefit in performing histogram analyses?

Purpose The apparent diffusion coefficient (ADC) is a potential prognostic imaging marker in rectal cancer. Typically, mean ADC values are used, derived from precise manual whole-volume tumor delineations by experts. The aim was first to explore whether non-precise circular delineation combined with histogram analysis can be a less cumbersome alternative to acquire similar ADC ...

Taking the history in patients with swallowing disorders: an international multidisciplinary survey

Purpose Clinical assessment of swallowing disorders (dysphagia) requires accurate and comprehensive medical history-taking to further tailor the diagnostic work-up, but functional health care questionnaires show a large variability and various limitations. The aim of this study was to assess the way in which international swallowing experts from various disciplines asses swallowing ...

Comparison of prone vs. supine unenhanced CT imaging in patients with clinically suspected ureterolithiasis

Purpose To retrospectively evaluate whether prone CT scanning is superior to supine scanning for correct localization of distal urinary calculi in patients with acute flank pain. Methods Consecutively performed unenhanced CT scans in patients with acute flank pain were retrospectively analyzed in 150 patients in supine and another 150 patients in prone position. Images were ...

Diffusion-weighted imaging for evaluating inflammatory activity in Crohn’s disease: comparison with histopathology, conventional MRI activity scores, and faecal calprotectin

Purpose To evaluate whether the extent of enteric diffusion-weighted imaging (DWI) signal abnormality reflects inflammatory burden in Crohn’s disease (CD), and to compare qualitative and quantitative grading. Methods 69 CD patients (35 male, age 16–78) undergoing MR enterography with DWI (MRE-D) and the same-day faecal calprotectin (cohort 1) were supplemented by 29 patients (19 ...

Comparison of clinical MRI liver iron content measurements using signal intensity ratios, R 2 and R 2*

Purpose To compare three types of MRI liver iron content (LIC) measurement performed in daily clinical routine in a single center over a 6-year period. Methods Patients undergoing LIC MRI-scans (1.5T) at our center between January 1, 2008 and December 31, 2013 were retrospectively included. LIC was measured routinely with signal intensity ratio (SIR) and MR-relaxometry (R 2 and R ...

FDG-PET/CT lymph node staging after neoadjuvant chemotherapy in patients with adenocarcinoma of the esophageal–gastric junction

Objectives The aim of the analysis was to assess the accuracy of various FDG-PET/CT parameters in staging lymph nodes after neoadjuvant chemotherapy. Methods In this prospective study, 74 patients with adenocarcinoma of the esophageal–gastric junction were examined by FDG-PET/CT in the course of their neoadjuvant chemotherapy given before surgical treatment. Data from the final ...

Shear wave elastography of the spleen: evaluation of spleen stiffness in healthy volunteers

Purpose The aim of this study was to assess the mean value of spleen stiffness measured by Shear wave elastography in healthy patients and its dependence on age, sex, and spleen dimensions, and to evaluate the repeatability of this method. Methods The final study group included 59 healthy volunteers without any clinical evidence of liver disease, portal hypertension, hematological ...

Diagnostic performance of contrast-enhanced multidetector computed tomography and gadoxetic acid disodium-enhanced magnetic resonance imaging in detecting hepatocellular carcinoma: direct comparison and a meta-analysis

The purpose of this study was to directly (head-to-head) compare the per-lesion diagnostic performance of contrast-enhanced computed tomography (CT) (also referred to as CT hereafter) and gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced magnetic resonance (MR) imaging (also referred to as MRI hereafter) for the detection of hepatocellular carcinoma (HCC). Studies reporting direct ...

MRI characteristics of proctitis in Crohn’s disease on perianal MRI

Purpose Multiple features have been described for assessing inflammation in Crohn’s disease (CD) in MR enterography, but have not been validated in perianal magnetic resonance imaging (MRI). Retrospectively, we studied which MRI features are valuable in assessing proctitis. Materials and methods CD patients (≥18 years) who underwent colonoscopy (reference standard) and perianal ...

Single-session alcohol sclerotherapy of symptomatic liver cysts using 10–20 min of ethanol exposure: no recurrence at 2–16 years of follow-up

Purpose To assess long-term results after single-session alcohol sclerotherapy of symptomatic benign liver cysts performed with maximum 20 min of exposure to alcohol. Methods We included 47 patients aged 32–88 years (42 women, 5 men) with 51 benign non-parasitic liver cysts that were exposed to ethanol for 7–20 min in a single sclerotherapy session and were followed for at least 24 ...
