Abstract Objectives The aim of this study is to improve the reliability subjective IQ assessment using a pairwise comparison (PC) method instead Likert scale in abdominal CT scans. Methods Abdominal scans (single-center) were retrospectively selected between September 2019 and February 2020 prior study. Sample variance was obtained by adding artificial noise dedicated reconstruction software, including reconstructions with filtered backprojection varying iterative strengths. Two datasets...
To prospectively determine the feasibility of diffusion tensor imaging (DTI) with fibre tractography as a tool for three-dimensional (3D) visualisation normal pelvic floor anatomy.Five young female nulliparous subjects (mean age 28 ± 3 years) underwent DTI at 3.0T. Two-dimensional diffusion-weighted axial spin-echo echo-planar (SP-EPI) pulse sequence was performed, additional T2-TSE multiplanar sequences anatomical reference. Fibre predefined and wall muscles performed offline by two...
The aim of this study was to assess the interobserver agreement magnetic resonance imaging (MRI)-based staging pelvic organ prolapse (POP) and quantify associations between MRI-based POP staging, findings at examination, floor symptoms. This a cross-sectional ten symptomatic patients, patients without POP, nulliparous asymptomatic women. Three different observers performed using pubococcygeal line (PCL), midpubic (MPL), perineal line, H as references. anterior middle compartment good...
Abstract Purpose The objective of this work was to characterise the dimensions knee focal cartilage defects, generate a heat map defect locations, and native articular surface morphology at most common sites aid in design generic resurfacing implants (FKRIs). Methods Healthy femoral segmented from magnetic resonance imaging scans 70 patients eligible for FKRI surgery. Cartilage defects were manually reconstructed create three‐dimensional (3D) models. A 3D statistical shape model created 200...
European Association of Urology guidelines recommend a risk-adjusted biopsy strategy for early detection prostate cancer in biopsy-naïve men. It remains unclear which is most effective. Therefore, we evaluated two risk assessment pathways commonly used clinical practice.To compare the diagnostic performance risk-based ultrasound (US)-directed pathway (Rotterdam Prostate Cancer Risk Calculator [RPCRC] #3; US volume assessment) and magnetic resonance imaging (MRI)-directed pathway.This was...
To prospectively explore the clinical application of diffusion tensor imaging (DTI) and fibre tractography in evaluating pelvic floor.Ten patients with organ prolapse, ten floor symptoms asymptomatic women were included. A two-dimensional (2D) spin-echo (SE) echo-planar (EPI) sequence was acquired. Offline morphological analysis magnetic resonance (MRI) performed. Inter-rater agreement for quality assessment tracking results evaluated using weighted kappa (κ). From agreed results, eigen...
Abstract Purpose: To investigate the feasibility of measuring motion in abdomen using a continuously tagged magnetic resonance imaging sequence. Materials and Methods: assess (nonperiodic) abdomen, nontriggered, transient field echo (TFE) sequence was implemented that acquires one complete 3D dataset per prepulse after fixed delay. In postprocessing, frequency analysis approach developed for compact reviewing data noise suppression. For proof principle, simulation made free‐breathing dynamic...
To evaluate continuously tagged 3 Tesla MRI for monitoring glucagon-induced bowel motility changes in healthy volunteers.After standardized oral preparation, 10 volunteers underwent a free-breathing, three-dimensional (3D) dynamic fast-field-echo (FFE), at 3.36 Hz sampling frequency. One milligram of glucagon was administered intravenously during data acquisition. Each dataset divided into four temporal sets 2 min (period 1 to 4). Taglines were tracked automatically using scale spaced based...
Patients with congenitally corrected transposition are at risk of right ventricular dysfunction and failure. With this in mind, we examined 13 patients transposition, 7 not having undergone surgery, 6 after physiological repair, comparing them healthy subjects matched for age sex, using cardiac magnetic resonance imaging, rest during dobutamine stress, order to determine regional global response stress. At rest, the had significantly decreased overall wall motion compared their peers (7.2 ±...
Objectives Cartilage defects (CDs) are regarded as early manifestation of osteoarthritis (OA). The infrapatellar fat pad (IPFP) is an important mediator in maintaining joint homeostasis, disease progression and tissue repair, with a crucial role its secreted proteins. Here, we investigate the proteome IPFP relation to clinical status response surgical treatment CDs.
A mesenteric cyst is a rare cause for abdominal pain. This umbrella term includes cystic entities which reside in the mesentery. We present case of an infected false 24-year-old female patient without prior surgery or known trauma. Mainstay treatment involves surgical resection, although less invasive treatments have been described. Prognosis depends on origin cyst.
Closed-loop small bowel obstruction (CL-SBO) can threaten the viability of intestine by obstructing a segment at two adjacent points. Prompt recognition and surgery are crucial.To analyze outcomes patients who underwent for CL-SBO to evaluate clinical predictors.Patients suspected CL-BSO on computed tomography (CT) single center between 2013 2019 were evaluated retrospectively. Patients divided into three groups perioperative outcome, including viable bowel, reversible ischemia, irreversible...
Heterotopic pancreas is a relatively uncommon congenital anomaly, defined as pancreatic tissue in ectopic sites without an anatomic and vascular continuity with the main body of pancreas. We report case 58-year-old woman who was admitted to hospital clinical suspicion mild, acute pancreatitis. Computed tomography, magnetic resonance imaging, transabdominal ultrasound, endoscopic ultrasound revealed normal orthotopic large heterotopic small bowel mesentery signs inflammation. The diagnosis...
A 61-year-old mountain hiker presented with acute pain of the medial-plantar aspect right foot. As location, intensity and onset were atypical for fasciitis plantaris, an ultrasound was performed. This demonstrated a segmental plantar vein thrombosis (PVT), which confirmed on consequent MRI. Patient non-smoker, without medical or family history coagulopathies. Four months previously, he suffered from metatarsalgia left, thus contralateral, foot, prompted treatment bilateral orthoses. In...
Magnetic resonance imaging of the colon is widely used for diagnosis and treatment anorectal disorders, but other applications can be considered as well. In this article we discuss application MRI in colorectal cancer, inflammatory bowel disease (Crohn’s ulcerative colitis) acute abdominal pain. The latter concerns without a specific preparation while two concern use distension (magnetic colonography). CT now principal technique these applications. major advantage over lack ionizing...
