Abstract
SUMMARY AND CONCLUSION The pancreas is a retroperitoneal organ in the upper abdominal cavity, so any solid pancreatic mass is discovered by a severe pain or it causes marked pressure on surrounding structures. esions are malignant, the greater percentage is for pancreatic ductal adenocarcinoma, while the solid benign pancreatic lesions are relatively rare as pancreatic focal pancreatitis. Differentiation between solid malignant lesions and focal pancreatitis is difficult as both lesions may mimic in the symptoms, signs and imaging which is sometime Unsatisfactory using ultrasonography, multi detector computed tomography (MDCT) and magnetic resonance imaging (MRI). So, New methods are required for early diagnosis. Our stud The most common solid pancreatic ly included 30 patients with solid pancreatic lesions. Patients with previous ultrasound or CT that reported solid pancreatic lesions, referred from departments of internal medicine, surgery, and oncology to the MRI units of Tanta University Hospitals. We exclude patients who had any contraindications for MRI as metallic implants such as (pacemaker or aneurysm clips), patients who had any contraindications for contrast as sensitivity for contrast or renal failure. Our MRI protocol is axial T1WI, axial T2WI, dynamic study via IV rapid bolus injection of 0.2 mmol/kg body weight of Gd-DTPA then flushing with a 20-mL saline through the IV catheter. Acquiring T1-weighted images after contrast. The dynamic series consist of one pre contrast followed by five post contrast series including 18s (early arterial phase), 45s (late arterial/pancreatic
