Background and Purpose- This study aims to investigate the association between characteristics of atherosclerotic plaques middle cerebral artery recurrent ischemic stroke using magnetic resonance vessel wall imaging. Methods- One hundred five patients with attributed plaque underwent high-resolution black-blood They were divided into group 1, first episode acute (imaging within 4 weeks stroke, n=44); 2, (n=29); 3, chronic after 3 months n=32). Plaque including area, burden,...
Prediction of isocitrate dehydrogenase (IDH) mutation status and epilepsy occurrence are important to glioma patients. Although machine learning models have been constructed for both issues, the correlation between them has not explored. Our study aimed exploit this improve performance IDH identification diagnosis in patients with II-IV. 399 were retrospectively enrolled divided into a training (n = 279) an independent test 120) cohort. Multi-center dataset 228) from The Cancer Imaging...
Background Conventional quantitative MRI (qMRI) scan is time‐consuming and highly sensitive to movements, posing great challenges for images of individuals with involuntary such as Huntington's disease (HD). Purpose To evaluate the potential our developed ultra‐fast qMRI technique, multiple overlapping‐echo detachment (MOLED), in overcoming head motion its capacity quantitatively assess tissue changes HD. Study Type Prospective. Phantom/Subjects A phantom comprising 13 tubes MnCl 2 at...
This study aims to investigate the feasibility of cellular microstructural mapping by diffusion MRI (IMPULSED, imaging parameters using limited spectrally edited diffusion) breast tumors, and further evaluate whether MRI-derived features is associated with prognostic factors in cancer. prospective collected 232 patients suspected tumors from March August 2023. The IMPULSED scan included acquisitions both pulsed (PGSE) oscillating (OGSE) gradient spin echo frequencies up 33 Hz. OGSE PGSE data...
Fluid-attenuated inversion recovery (FLAIR) is indispensable in MRI-based head-and-neck assessments, but its quantitative counterpart remains clinically absent due to the influence of cerebrospinal fluid (CSF) dynamics and lengthy acquisition time spent on a series weighting-increasing images. This work implements validates fast fluid-attenuated T2 (FLA-T2) mapping via inversion-recovery-prepared multiple overlapping-echo detachment imaging (IR-MOLED). The clinical value prospectively...
To analyze the value of amide proton transfer (APT) weighted and intravoxel incoherent motion (IVIM) imaging in evaluation prognostic factors for rectal adenocarcinoma, compared with diffusion (DWI).Preoperative pelvic MRI data 110 patients surgical pathologically confirmed diagnosis adenocarcinoma were retrospectively evaluated. All underwent high-resolution T2-weighted (T2WI), APT, IVIM, DWI. Parameters including APT signal intensity (APT SI), pure coefficient (D), pseudo-diffusion (D*),...
Background and purpose The differential diagnosis between solid glioma brain inflammation is necessary but sometimes difficult. We assessed the effectiveness of multiple diffusion metrics diffusion-weighted imaging (DWI) in differentiating from compared diagnostic performance different DWI models. Materials methods Participants diagnosed with either or a lesion on MRI were enrolled this prospective study May 2016 to April 2023. Diffusion-weighted was performed using spin-echo echo-planar...
Background The application value of T 2 mapping in evaluating cervical cancer (CC) features remains unclear. Purpose To investigate the role values CC classification, grade, and lymphovascular space invasion (LVSI) comparison to apparent diffusion coefficient (ADC), compare synthetic ‐weighted (T W) images calculated from conventional W for staging. Study Type Retrospective. Population Sixty‐three patients with histopathologically confirmed CC. Field Strength/Sequence 3T, turbo spin‐echo,...
Background Numerous studies have indicated altered temporal features of the brain function in Parkinson's disease (PD), and autocorrelation magnitude intrinsic neural signals, called timescales, were often applied to estimate how long information stored local areas. However, it is unclear whether PD patients at different stages exhibit abnormal timescales accompanied with gray matter volume (GMV). Purpose To assess timescale GMV PD. Study Type Prospective. Population 74 idiopathic (44 early...
Abstract We report two cases with tiny ferromagnetic intraocular foreign bodies (FBs) that were demonstrated only on magnetic resonance imaging (MRI) and confirmed by subsequent ophthalmologic operation. Both of the patients had a history ocular trauma their clinical symptoms compatible an FB. Plain x‐ray film, 3 mm slice thickness computed tomography (CT) scans (Toshiba TXT 600 system GERP22 system), B‐scan ultrasonography, MRI study (Siemens Impact 1.0 MR system) acquired. examinations...
Diffusion-weighted MRI (DWI) has been introduced in head and neck lesions adds important information to the findings obtained through conventional MRI. The purpose of this study was assess role DWI differentiating benign malignant tongue at 3.0-T field strength imaging.78 patients with 78 lingual underwent b-values 0 1000 s mm(-2) before therapy. apparent diffusion coefficient (ADC) maps were reconstructed, ADC values calculated compared between tongue.The mean tumours, solid cystic...
