Article Synopsis
  • The study aimed to create and validate a machine learning model using multiparameter MR imaging to predict pathological complete response (pCR) in locally advanced rectal cancer patients after neoadjuvant chemoradiotherapy.* -
  • It involved 151 patients split into internal and external validation sets, employing various classifiers, like random forest and support vector machine, to evaluate predictive accuracy through metrics like the ROC curve.* -
  • Results showed that the random forest model outperformed other classifiers, yielding high accuracy and promising predictive performance, indicating its potential for improving management strategies for LARC patients.*

Objective: To evaluate the performance of intravoxel incoherent motion (IVIM) diffusion-weighted MR imaging in the differential diagnosis of Angiomyolipoma (AML), clear cell renal cell carcinoma (clear cell RCC) and non-clear cell renal cell carcinoma (non-clear cell RCC).

Method: Forty-five patients were enrolled and classified into three groups according to the surgical pathology results. There were even amount of subjects (15) in each group of AML group, clear cell RCC group and non-clear cell RCC group (including 6 Papillary RCC and 9 Chromophobe RCC).

Background: Coronal diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values have gradually become applied (following conventional axial DW-MRI) in the renal analysis. To explore whether data obtained using coronal DW-MRI are comparable with those derived using axial DW-MRI, this preliminary study sought to assess the agreement in renal ADC values between coronal DW-MRI and axial DW-MRI.

Methods: Thirty-four healthy volunteers were enrolled in the study; written consents were obtained.

Objective: To evaluate the changes of ADC value on renal parenchyma at different age groups in healthy adults.

Methods: One hundred healthy adults were divided into five groups based on age:namely 18-29 years, 30-39 years, 40-49 years, 50-59 years and 60-69 years. All adults underwent diffusion-weighted magnetic resonance(MR) imaging of the kidneys with b values of 800 s/mm(2).

Objective: To document the magnetic resonance (MR) imaging features of multifocal clear cell renal cell carcinoma (RCC).

Methods: The MR findings of 11 cases of pathologically-proved multifocal clear cell RCCs were reviewed retrospectively from January 2008 to December 2010. All patients underwent MR in a 1.

Objective: To document the MRI features of Chromophobe cell carcinoma and to explore whether MR features vary with the tumor size.

Methods: MRI features of 34 patients (16 male, 18 female, age range from 24 - 61, average age is 49 years old), totally 35 focuses with histologically proved chromophobe cell carcinoma were studied retrospectively. All the patients underwent MR plain and dynamic contrast-enhanced scan before their surgery.
