PURPOSE There is wide inter-institutional variation in the interval between neoadjuvant chemoradiotherapy (NACRT) and surgery for locally advanced rectal cancer. We aimed to assess the association of magnetic resonance imaging (MRI) at 9 and 14 weeks post-NACRT; T-staging (ymrT) and post-NACRT tumour regression grading (ymrTRG) with histopathological outcomes; histopathological T-stage (ypT) an...
Transitional cell carcinoma(T.C.C) of bladder display an upredictable biological behavior.Morphologic methods of grading this tumor are insuficient to predict the clinical outcome of the patients.the aim of this study was to investigate the relationships between histological grading staging and DAN ploidy especially in intermediate grade II(IIa and IIb). in a retrospective study of tissue spec...
conclusions the results showed that clinical and ultrasonographic grading to diagnose varicoceles is directly consistent together and it is possible to make them equivalent together. in addition, the age factor has not a significant impact on disease grading. methods in this cross-sectional study, 66 patients suspected of varicocele referred to urology clinic of shahid faghihi hospital in shira...
Medical Image segmentation is to partition the image into a set of regions that are visually obvious and consistent with respect to some properties such as gray level, texture or color. Brain tumor classification is an imperative and difficult task in cancer radiotherapy. The objective of this research is to examine the use of pattern classification methods for distinguishing different types of...
OBJECTIVE To compare magnetic resonance imaging (MRI), conventional radiography, and ultrasonography in identifying bone erosions in patients with juvenile idiopathic arthritis (JIA), and to determine the validity and reliability of an MRI scale in detecting and grading joint damage. METHODS In 26 JIA patients, the clinically more affected wrist was studied with MRI, radiography, and ultrason...
Background: To retrospectively describe imaging characteristics of liver metastases on fused FDG-PET/ MRI data sets and to compare the diagnostic accuracy of MRI and fused FDG-PET/MRI data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. Materials and Methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by FDG-PET...
Magnetic resonance imaging, MRI, offers a wide range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow-ups, or assessment of treatment response. In the past decade, there has been an increased interest in quantitative imaging, which give repeatable measurements...

Introduction The objective of this guideline is to outline the role of magnetic resonance imaging (MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury (SCI). Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI. This review focused on longitudinal studies ...
Medical imaging has a remarkable role in the practice of clinical medicine. This study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend Shiraz University of Medical Sciences, Shiraz, Iran. We conducted across-sectional survey using a self-administered qu...
