Evaluation of diagnostic value and T2-weighted three-dimensional isotropic turbo spin-echo (3D-SPACE) image quality in comparison with T2-weighted two-dimensional turbo spin-echo (2D-TSE) sequences in lumbar spine MR imaging
Conclusion3D SPACE sequence for lumbar spine MRI proved to have higher SNR, CNR, and visibility for all regions of lumbar spine except vertebrae and disc. Inter-observer and inter-method agreements for pathologic indexes between 3D SPACE and 2D TSE sequences were substantial and 3D SPACE had a higher inter-observer agreement and less scan time. Therefore, T2 weighted 3D SPACE sequence, and its MPR might be an excellent alternative for 2D TSE in sagittal, axial, and coronal planes, especially for patients with abnormal curvature of the lumbar spine.

Sulcal FLAIR hyperintensity after CSF removal in two patients with intracranial hypertension
Publication date: 2019Source: European Journal of Radiology Open, Volume 6Author(s): Milad Yazdani, Seth T. Stalcup, Arindam R. Chatterjee, Maria G. MatheusAbstractSulcal hyperintensity on fluid-attenuated inversion recovery (FLAIR) sequence is a frequently encountered finding that could be due to an abnormality of cerebrospinal fluid, a secondary finding related to an intracranial pathologic process, or be artifactual or iatrogenic. Here we present two cases of sulcal FLAIR hyperintensity in the setting of intracranial hypotension after CSF removal for intracranial hypertension. (Source: European Journal of Radiology Open)

The effect of vertical centering and scout direction on automatic tube voltage selection in chest CT: a preliminary phantom study on two different CT equipments
ConclusionsPatient vertical off-centering and scout direction affected substantially the CTDIvol and image quality in chest CT examinations. Vertical off-centering caused variation also in the selected tube voltage. The function of ATVS and TCM methods differ significantly between the CT vendors, resulting in differences in CTDIvol and image noise characteristics. (Source: European Journal of Radiology Open)

Efficacy of diffusion tensor imaging in identification of degenerative cervical spondylotic myelopathy
ConclusionFA and ADC values enhance the efficacy and accuracy of MRI in the diagnosis of cervical spondylotic myelopathy. Hence diffusion tensor imaging can be used as a non-invasive modality to recognize spondylotic myelopathy changes even in the early stages, which can be helpful in deciding on appropriate timing of decompression surgery before the irreversible chronic changes set in.

Strategy for the treatment of spontaneous isolated visceral artery dissection
ConclusionsSymptomatic SIVAD patients should be hospitalized because some of those may experience organ ischemia or aneurysm formation. Endovascular intervention is a feasible treatment for complications of SIVAD. (Source: European Journal of Radiology Open)

MR Imaging of hypoxic ischemic encephalopathy – Distribution Patterns and ADC value correlations
ConclusionsDue to significant increase in ADC values of affected white matter, ADC value can be used as a marker to detect chronic sequel of hypoxic ischaemic brain injury. Another observation was the perirolandic brain tissue being most common area of involvement in the cases with cerebral palsy. (Source: European Journal of Radiology Open)

Evaluation of ADCratio on liver MRI diffusion to discriminate benign versus malignant solid liver lesions
Conclusion:Our dataset indicates that lesion to background liver ADCratio is superior in discriminating between benign and malignant focal lesions compared to absolute ADC values of the hepatic lesions. (Source: European Journal of Radiology Open)

Review of diffuse cortical injury on diffusion-weighted imaging in acutely encephalopathic patients with an acronym: “CRUMPLED”
Conclusion"CRUMPLED" is proposed as a convenient acronym for the categorization of a diverse range of acute etiologies associated with DCI on DWI, arising from varying degrees of cytotoxic edema. These etiologies can range from being potentially reversible (e.g. hyperammonemia or prolonged seizures) to irreversible (e.g. hypoxic-ischemic injury). (Source: European Journal of Radiology Open)

Chest pain CT in the emergency department: Watch out for the myocardium
ConclusionHM indicating acute MI are often encountered in chest pain CT in the ED, also in chest-pain CTw/o coronary when MI is not suspected. This indicates that the myocardium should always be analyzed for hypodense regions even when MI not suspected. (Source: European Journal of Radiology Open)

Optimizing diffusion-weighted magnetic resonance imaging for evaluation of lung tumors: A comparison of respiratory triggered and free breathing techniques
ConclusionsNo difference in ADC measurement or repeatability between FB and RT DWI in whole lesion ADC measurements of adenocarcinomas in the lung was demonstrated. The results imply that in this setting the FB acquisition method is accurate and possibly more robust than the RT acquisition technique. (Source: European Journal of Radiology Open)

Distinction between phyllodes tumor and fibroadenoma in breast ultrasound using deep learning image analysis
ConclusionDeep learning based image analysis may be able to exclude PT with a high negative predictive value. Integration into the clinical workflow may enable radiologists to more confidently exclude PT, thereby reducing the number of unnecessary biopsies. (Source: European Journal of Radiology Open)

Imaging findings and complications of transcatheter interventional treatments via the inferior phrenic arteries in patients with hepatocellular carcinoma
ConclusionsTranscatheter arterial chemoembolization or transcatheter arterial embolization via the inferior phrenic artery in patients with hepatocellular carcinoma was relatively safe. Shoulder pain was the most frequent complication, and required only conservative treatment. There was no clear connection between pleural effusion or basal atelectasis and collateral circulation from the right inferior phrenic artery to the pulmonary artery depicted on angiography, computed tomography during angiography or post-procedure computed tomography.

Hilly or mountainous surface: a new CT feature to predict the behavior of pure ground glass nodules?
Publication date: 2018Source: European Journal of Radiology Open, Volume 5Author(s): Andrea Borghesi, Silvia Michelini, Francesco Bertagna, Alessandra Scrimieri, Stefania Pezzotti, Roberto MaroldiAbstractPersistent pure ground-glass nodules (pGGNs) typically show an indolent course with very slow growth rates. These slow-growing lesions exhibit different growth patterns regardless of their initial computed tomography (CT) features. Therefore, predicting the aggressive behavior of pGGNs on initial CT remains a diagnostic challenge. The literature reports that computerized analysis and various quantitative features have been...
