Diffusion-derived vessel density (DDVD) is a physiological surrogate of the area micro-vessels per unit tissue area. DDVD calculated according to: DDVD(b0b5) = Sb0/ROIarea0 - Sb5/ROIarea5, where Sb0 and Sb5 refer to signal when
To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) rectal cancer. A retrospective analysis was conducted on 70 patients with cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment subsequent surgery between March 2019 December 2022. The morphological characteristics MLNs, along quantitative parameters derived DCE-MRI (Ktrans, kep, ve) DWI (ADCmin,...
Background Pleomorphic xanthoastrocytoma (PXA) is a rare and special type of astrocytoma which occurs in childhood adolescence, usually with favorable prognosis. Since its initial description, PXA cases have been reported infrequently the literature, mostly as single or small series. Purpose To review imaging characteristics PXA. Material Methods MR findings 19 pathologically confirmed PXAs were retrospectively analyzed correlated clinical pathological features. Results The presentation 18...
To determine whether magnetic resonance imaging (MRI)-detected extramural vascular invasion (mrEMVI) status is associated with quantitative perfusion parameters derived from dynamic contrast-enhanced MRI (DCE-MRI) in rectal cancer. Seventy-two patients adenocarcinoma who underwent curative surgery alone within 2 weeks following were enrolled this retrospective study. mrEMVI was determined based on high-resolution MRI. The (Ktrans, kep and ve) DCE-MRI calculated all sections containing...
Abstract Background After neoadjuvant therapy, most of the lymph nodes (LNs) will shrink and disappear in patients with rectal cancer. However, LNs that are still detectable on MRI carry a risk metastasis. This study aimed to evaluate performance European Society Gastrointestinal Abdominal Radiology (ESGAR) criterion (short-axis diameter ≥ 5 mm) diagnosing malignant cancer after whether nodal morphological characteristics (including shape, border, signal homogeneity, enhancement homogeneity)...
BACKGROUND Comprehensive and precise assessment of rectal carcinoma is crucial before surgery to plan an individual treatment strategy. New functional techniques, such as intravoxel incoherent motion (IVIM), have emerged could lead more detailed information. The aim this study was evaluate the difference between tumor parenchyma normal wall by IVIM explore correlations parameters histopathology. MATERIAL AND METHODS We prospectively enrolled 128 patients with pathologically proven...
The aim of this study was to discriminate metastatic from nonmetastatic regional lymph nodes (LNs) with short-axis diameters less than 5 mm in rectal cancer using quantitative parameters derived dynamic contrast-enhanced (DCE) MRI.Sixty-five LNs 122 patients were evaluated, including malignant (n = 27) and benign 38). following assessed: the forward volume transfer constant (Ktrans), reverse (kep), fractional extravascular extracellular space (Ve), diameter, long-axis short- diameter ratio....
Intravoxel incoherent motion magnetic resonance imaging (IVIM-MRI) acquires tumor perfusion information without injection of contrast medium, which is promising in assessment. However, its consistency with dynamic contrast-enhanced MRI (DCE-MRI), a more widely used method for evaluation, not revealed rectal cancer.In this study, we aimed to investigate the correlation perfusion-sensitive parameters derived from IVIM-MRI DCE-MRI and measurement reproducibility cancer.Forty-seven cancer...
To evaluate the diagnostic performance of diffusion kurtosis imaging (DKI) for distinguishing different histopathological subtypes and grades rectal carcinoma to compare DKI with conventional diffusion-weighted (DWI). This prospective study involved 132 patients carcinoma, comprising 116 adenocarcinoma not otherwise specified (AC) 16 mucinous (MC). High spatial resolution magnetic resonance (MR) sequences (b values 0, 600, 1000, 1500 2000 s/mm2) were performed pretreatment evaluation. The...
Abstract Background The aim of this study is to evaluate the microstructure and microcirculation regional lymph nodes (LNs) in rectal cancer by using non-invasive intravoxel incoherent motion MRI (IVIM-MRI), distinguish metastatic from non-metastatic LNs quantitative parameters. Methods All recruited patients underwent IVIM-MRI ( b = 0, 5, 10, 20, 30, 40, 60, 80, 100, 150, 200, 400, 600, 1000, 1500 2000 s/mm 2 ) on a 3.0 T system. One hundred sixty-eight with short-axis diameter equal or...

To investigate the application value of fat-suppressed gadolinium-enhanced isotropic high-resolution 3D-GRE-T1WI in regional nodes with different short-axis diameter ranges rectal cancer, especially ≤5 mm.Patients adenocarcinoma confirmed by postoperative histopathology were included, and all patients underwent preoperative 3.0 T magnetic resonance imaging (MRI) total mesorectal excision (TME) within 2 weeks after an MR scan. The harvested from specimens matched field view (FOV) images for a...
Motivation: Orthogonal axial images (OAI), which may improve staging performance, had been ignored in previous studies about gastric cancer (GC) T-staging using MRI. Goal(s): To assess the value of MR OAI GC preoperative T-staging. Approach: Diagnostic performance metrics, over- and understaging fractions, overall accuracy (compared by McNemar test) for MRI lacking or incorporating MDCT were quantified referring to pathological T-stage. Results: The was significantly higher with than those...
