Can Multidetector Ct Scan Replace Mri For Evaluation Of Mesorectal Fasca In Rectal Cancer?, Maryam Farghdani, Mehdi Karami, Amirafraz Fallah

BioMedicine

Abstract

Background

Colorectal cancer is the 4th leading cause of cancer mortality.

Aim

This study aimed to can multidetector CT scan (MDCT) replace Magnetic resonance imaging (MRI) for mesorectal fasca in rectal cancer?

Methods

This cross-sectional was conducted on patients with rectal cancer in Alzahra and Seyed-Shohada hospitals. MRI, mesorectal fascia (MPR), and axial MDCT were provided from patients to assess the involvement of mesorectal fascia. Sensitivity, specificity, positive and negative predictive values were assessed in these patients. Kappa coefficient agreement was used for analysis. Patients were also divided into different subgroups based on gender, tumoral location, nodal involvement, and …

Evaluation Of Subacute Subarachnoid Haemorrhage Detection Using A Magnetic Resonance Imaging Sequence: Double Inversion Recovery, Zahra Mardanshahi, Maryam Tayebi, Sajad Shafiee, Maryam Barzin, Misagh Shafizad, Reza Alizadeh-Navaei, Abdolmajid Gholinataj

BioMedicine

Background and Objectives: The diagnosis of subarachnoid hemorrhage (SAH) especially at the subacute stage is still a challenging issue using the conventional imaging modalities. Here we evaluated the role of double inversion recovery (DIR) sequence of MRI compared with the conventional gradient-recalled echo (GRE)-T2*-W and susceptibility-weighted imaging (SWI) sequences in the diagnosis of subacute SAH.

Materials and Methods: This prospective study was conducted on 21 patients with SAH, which were diagnosed using CT scan at the initial step. In the third week after the injury (14-20 days), all patients underwent a brain MRI exam that included T2*-W, SWI, and …
