Diagnostic Confidence and Feasibility of a Deep Learning Accelerated HASTE Sequence of the Abdomen in a Single Breath-Hold

Objective The aim of this study was to evaluate the feasibility of a single breath-hold fast half-Fourier single-shot turbo spin echo (HASTE) sequence using a deep learning reconstruction (HASTEDL) for T2-weighted magnetic resonance imaging of the abdomen as compared with 2 standard T2-weighted imaging sequences (HASTE and BLADE). Materials and Methods Sixty-six patients who underwent 1.5-T liver magnetic resonance imaging were included in this monocentric, retrospective study. The following T2-weighted sequences in axial orientation and using spectral fat suppression were compared: a conventional respiratory-triggered BLADE sequence (time of acquisition [TA] = 4:00 minutes), a conventional multiple breath-hold HASTE sequence (HASTES) (TA = 1:30 minutes), as well as a single breath-hold HASTE with deep learning reconstruction (HASTEDL) (TA = 0:16 minutes). Two radiologists assessed the 3 sequences regarding overall image quality, noise, sharpness, diagnostic confidence, and lesion detectability as well as lesion characterization using a Likert scale ranging from 1 to 4 with 4 being the best. Comparative analyses were conducted to assess the differences between the 3 sequences. Results HASTEDL was successfully acquired in all patients. Overall image quality for HASTEDL was rated as good (median, 3; interquartile range, 3–4) and was significantly superior to HASTEs (P

Authors: Kim EH, Shim WH, Lee JS, Yoon HM, Ko TS, Yum MS Abstract BACKGROUND AND PURPOSE: Recent quantitative neuroimaging studies of childhood absence epilepsy (CAE) have identified various structural abnormalities that might be involved in the onset of absence seizure and associated cognitive and behavioral functions. However, the neuroanatomical alterations specific to CAE remain unclear, and so this study investigated the regional alterations of brain structures associated with newly diagnosed CAE. METHODS: Surface and volumetric magnetic resonance imaging data of patients with newly diagnosed CAE (n=18) an...

CONCLUSIONS: Paramagnetic rims might be a characteristic MRI finding for MS, and therefore they have potential as an imaging marker for differentially diagnosing MS from NMOSD using 3-T MRI. PMID: 33029961 [PubMed]

CONCLUSION: GA-MRI is an effective noninvasive method that may be useful for the differentiation of NASH from isolated steatosis, and could help to avoid liver biopsy in patients with NAFLD. PMID: 33033571 [PubMed]

Conclusion: Although treatment algorithms are an attractive tool to guide clinicians and resource allocation, they need to take into account the local population characteristics before routine implementation. Level of Evidence: Level IV–retrospective cohort study.

This study sought to report on the impact of insurance type on access to and results of knee MRI in pediatric sports medicine patients. Methods: A retrospective review of 178 consecutive pediatric sports medicine clinics was completed. Inclusion criteria: patients younger than 18 years, routine knee MRI ordered, sports medicine diagnosis, and insurance. Data included basic demographics, injury date, date and location (urgent care vs. clinic) of the first presentation, details of MRI ordering and approval, date and location of MRI follow-up, MRI results (negative, minor findings, major findings), and eventual treatment r...

Study Design. A prospective study of patients originally randomized to total disc replacement (TDR) or multidisciplinary rehabilitation. Objective. To assess the long-term development of facet arthropathy (FA) after TDR versus nonoperative treatment, and to analyze the association between FA and clinical outcome. Summary of Background Data. FA may appear or increase following TDR, but the natural course of FA is unclear, and no previous study has evaluated the long-term development of FA following TDR compared with nonoperative treatment. Methods. The study included 126 patients with chronic low back pain and de...

Study Design. A registry-based comparative cohort study with 2-year follow-up. Objective. To assess whether Modic changes (MCs) are associated with health-related quality of life, long-term physical disability, back- or leg pain after discectomy. Summary of Background Data. Previous studies have failed to show a clinically significant association between MCs and patient-reported outcomes (PROs) after discectomy. Methods. Data from the Danish National Spine Registry on patients undergoing first-time lumbar discectomy at a single institution from 2014 to 2017 with an accessible preoperative lumbar magnetic resonan...

Study Design. Retrospective study. Objective. We identified radiological risk factors for neurological deficits in mid and low lumbar spinal fractures. Summary of Background Data. Although numerous studies have focused on radiological risk factors for neurological deficits in spinal cord injury or thoracolumbar junction area fractures, few have examined mid and low lumbar fractures at the cauda equina level. Methods. We retrospectively reviewed 71 consecutive patients who suffered acute traumatic mid and low lumbar fractures (L2–L5) corresponding to the cauda equina level, as confirmed on magnetic resonanc...

Authors: Erbel R Abstract The progress in cardiology during the last 50 years can best be studied by looking at the diagnostics and treatment of patients with aortic valve stenosis. Previously, the clinical examination, electrocardiography (ECG) and chest X‑ray were used before heart catheterization, which included a transseptal puncture to complete the indications for surgery in young patients. Nowadays, echocardiography, often combined with a dobutamine stress test, is the primary diagnostic tool to which computed tomography for quantification of valve calcification and cardiac magnetic resonance...
