While the subjective image quality and detectability of DJD lesions were not significantly different from standard reconstructions, the preference of readers for DLM images indicates potential benefits that could enhance the diagnostic capabilities in TMD evaluation. Summary Objective Due to the high signal intensity of cerebrospinal fluid (CSF), proton density-weighted (PD-w) images with long repeat times (TR) may be less able to detect periventricular lesions in patients with multiple sclerosis (MS). However, we have found good detectability of MS lesions with PD-w using long TR at 3 Tesla (3 T). Deep learning (DL) accelerated controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA)-volumetric interpolated breath-hold examination (VIBE), provides high spatial resolution T1-weighted imaging of the upper abdomen. We aimed to investigate whether DL-CAIPIRINHA-VIBE can improve image quality, vessel conspicuity, and

Download scientific diagram | CT urogram multiplanar volume-rendered (MPVR) coronal reformation showing ureters in white, with normal peristalsis, hence incompletely seen the moment this CT was Multiplanar reformation images from CS isotropic data contain image contrast identical to that obtained in the initial acquisition plane. CS can provide images in any obliquity from the data sets obtained during critical phases of enhancement (arterial, portal venous and delayed phases of liver enhancement, for example). Noise from thin slice thickness can be reduced to improve low-contrast lesion detectability by increasing radiation doses to increase SNR, using soft reconstruction kernels, applying various data filters, adjusting window and level settings, and utilizing sliding-thin-slab averaging.

In the first step, prospective data were analyzed for lesion detectability by calculating the sensitivity, specificity, and accuracy and for lesion characterization by calculating the correlation to the standard of reference by means of Spearman’s rank correlation test. In the second step, retrospective data were analyzed.

Background Deep learning image reconstruction (DLIR) algorithms allow strong noise reduction while preserving noise texture, which may potentially improve hypervascular focal liver lesions. Purpose To assess the impact of DLIR on image quality (IQ) and detectability of simulated hypervascular hepatocellular carcinoma (HCC) in fast kV-switching dual-energy CT Round 1 Reviewer 1 Report Comments and Suggestions for Authors This is nice and fair study aiming to evaluate the detectability of iodine in mediastinal lesions with photon counting CT compared to conventional CT. Similar studies has been already performed before (not only for CCT, but also for DECT). As expected (and already shown before) substantial PurposeTo evaluate the role of 64 multidetector CT (MDCT) with multiplanar reformation in evaluation of bilateral ovarian masses and to correlate the findings with histopathological results and

Summary The abdominal cocoon is a rare cause of intestinal obstruction that is usually diagnosed at the time of laparotomy. We report a case, show the features of MDCT scanning with multiplannar reformation, and discuss the preoperative diagnostic clues obtained by radiologic imaging and pathologic correlation. We propose a system that automatically generates multiplanar reformation (MPR) images on-the-fly, which is independent of computed tomography (CT) scanner type. Triggered by digital imaging communication in medicine (DICOM) Storage Commitment or in Multiplanar reformation. In multiplanar reformation, the points of the plane crossing the volume are obtained by interpolation from the known points of the volume.

Since the common task of diagnostic CT scan images is the visual detection of lesions, detectability performance is an important measure of image quality [18]. The theory behind LCD implies that the detectability of details increases with the increasing size of objects or contrast between objects and their background [14], [19]. In 68 lesions that were removed at surgery, the detectability of early and advanced gastric cancers and the accuracy of classification of gross appearance and serosal invasion as determined with

-MPR (Multiplanar reformation) coronal and sagittal planes of a CT examination of bone structures, from the thoracic aperture to femoral distal metaphysis (A, B, C and D) and 3D (E, F), presenting Herein, we present three cases of ICG excretory defect, which showed impaired lesion detectability on gadoxetic acid-enhanced MR imaging (EOB-MRI). In the hepatobiliary phase (HBP) of EOB-MRI, diminished enhancement of the liver parenchyma, prolonged intravascular enhancement, and attenuated gadoxetic acid excretion to the bile duct were observed. New sequences, such as FREEZEit StarVIBE and CAIPIRINHA VIBE, enable high-resolution, temporal and spatial, 3D dynamic studies [4, 5, 8]. The 3D acquisitions allow multiplanar refor-mats for better detection of very small (even sub-millimeter) lesions while the high temporal resolution imaging provides better sensitivity to detect

In both prospective reconstructed axial images and multiplanar reformation images, detection of pancreatic lesion, extent of lesion, and vascular and bile ductal changes were analyzed with a grading system of 1,2, 3.

Multiplanar reformation or reconstruction (MPR) involves the process of acquiring defined diagnostic slices of information from volumetric data achieved during the scanning process. The volumetric data is commonly referred to as the ‚volume‘ or The lesion detectability was the percentage of identifiable lesions in the groups of 180 to 18 s using the group 900 s as reference. Results: Our results showed that sufficient and acceptable subjective image quality could be achieved with 60- and 30-s groups, and good image quality scores were given to 180- and 120-s groups without The objective of our study was to compare the diagnostic accuracy of virtual cystoscopy, multiplanar reformation, and source CT images for lesion detection in the contrast material-filled bladder.

Abstract Enhanced z-axis coverage with thin overlapping slices in breath-hold acquisitions with multidetector CT (MDCT) has considerably enhanced the quality of multiplanar 3D reconstruction. This pictorial essay describes the improvements in 3D reconstruction and technical aspects of 3D reconstruction and rendering techniques available for abdominal imaging. Clinical applications The development of multiplanar reformation in multidetector computed tomography (MPR-MDCT) and fast imaging with steady-state precession (FISP) magnetic resonance cholangiopancreatography (MRCP) has greatly advanced imaging of the duodenal and hepatobiliary region and has improved the visibility of duodenal diverticulum and distal

It has been suggested that multiplanar reformation (MPR) technique of multislice CT (MSCT) can help elucidate the relationship between the location of the tumor and bronchi, in addition to better characterizing the lesion itself, thus facilitating in narrowing the differential diagnosis and diagnosis of tracheobronchial lesions. [2–5] This 1. To prevent excessive increase in dose, a higher noise content can be tolerated in thin-collimated CT datasets applying STS averaging for detection of low contrast lesions. Spatial resolution is retained. 2. Optimal slab thickness for STS averaging is dependent on lesion size. 3. Noise suppression with STS averaging is more effective using multiplanar reformations than on

The aim of this retrospective study was to compare accuracies of axial, multiplanar, and volume-rendered 3-dimensional (3D) images in the diagnosis of costal bone lesions. Forty-one patients, aged from 10 to 72-years old, with costal bone lesions Download scientific diagram | Multiplanar reformation view. It shows automatically segmented RCT lesion (red area). Segmented area can be viewed two dimensionally in multiplanar (coronal, axial In the first step, prospective data were analyzed for lesion detectability by calculating the sensitivity, specificity, and accuracy and for lesion characterization by calculating the correlation to the standard of reference by means of Spearman’s rank correlation test. In the second step, retrospective data were analyzed.

If necessary, multiplanar reformation (MPR) images are also available with projections oriented perpendicular to the probable gastric lesions detected on the VE images. Recent advances in multi-detector ct (mdct) technology allow for the acquisition of volumetric data with isotropic voxel size permitting reconstructions in any plane of section. These post-processing techniques have proven to be of benefit in the evaluation of temporal bone pathology. This chapter demonstrates some of the optimal imaging planes that can be used to
