Abstract
The MRI applications increasingly use in diagnosis and management of the pancreatic tumors, the study aim is to view the value of DW MRI in the diagnosis of pancreatic neoplasm and to compare the results of DW MRI with that of CE-MRI.
Contrast administration is invasive and time-consuming in addition to the adverse effects of contrast. Also, many cancer patients have already impaired renal functions. With the development of high field magnets and great advances in functional MRI, DWI is increasingly used as in the detection and characterization of abdominal tumours.
In our DWI study, b values were 0, 300& 600 sec/mm2, with the application of parallel imaging and breath triggering technique, a satisfying image quality has been achievable on a 1.5-T scanner within an acceptable acquisition time.
A retrospective study, conducted from 2018 and 2019 .Any age group and sex that diagnosed with pancreatic tumors.. Sample is 40 cases including 5 benign have nonmalignant MRI lesions while 35 patients have malignant MRI findings.
Forty patients were included in this study, 24 males (60%) and 16 females (40%). The patient’s age was ranging from 24 to 86 years with mean age of 52.48 ± 15.88 years.
limitations in this study. First, the small study population, the larger samples size are needed to confirm our results. Second, the study included very limited nonmalignant cases so no reliable specify or negative predictive value can be calculated. Last the presence of respiratory motion-related artifacts was unavoidable in uncooperative patients with an irregular respiratory rhythm. These artifacts might cause errors to ADC value measurement.
