Study of Pulmonary Embolism Using Multi-detector Computed Tomography (MDCT)

Abstract

This was a descriptive study designed to cross secttion discription pulmonary embolism patients in the sudanese population using MDCT the study was carried out and the data will be collected from Ribat University Hospital in Khartoum state with a suspicion of pulmonary embolism in the during the period from Feb 2017 to Jun 2017.The study sample size ware 78patients (33 male and 45 female), the average age of the male 57 years and the female 42 years. Pulmonary embolism is a common and potentially fatal disorder although CT pulmonary angiography is best and easiest method widely used to evaluation pulmonary embolism segmental and peripheral (subsegmental) embolisms, so the researcher try to find the pulmonary embolism feature or study in the Sudanese population using MDCT. To characterize the common gender who have a pulmonary embolism, To characterize the common age group that have a highly incidents rate by a pulmonary embolism, To evaluate the recurrent probability in the patient who have a previous history of pulmonary embolism, To discover the risk of pulmonary embolism in the postoperative patients, To determine the common location of pulmonary emboli. Patient’s laboratory result of the renal function tests most be in the normal , all patients were asked to continue adequate simple fluid intake up to 3 hours prior to examination to ensure adequate hydration, patients were taught how to hold breath during examination when requested, to ensure their cooperation and then underwent CT pulmonary angiography with a multi-detector row CT scanner. The age group have probability of pulmonary embolism was 61-70 year old, the probability of pulmonary embolism incidence increased by a previous patients family history, the postoperative and prolong bed rest patients is one of patients whom at ricky of pulmonary embolism, the common side of pulmonary embolism is in the right pulmonary artery, bilateral and in the left pulmonary artery respectively, the study shows the common location of pulmonary embolism, was in the periphery of the pulmonary vessels and less prevalence in the large central vessels patients.A large sample size is needed for further study of the pulmonary embolism patients, pulmonary CTA is a good stander modality in detection of pulmonary embolism but still need another investigation to support the diagnosis. Using a modified technique in pulmonary CTA by adding a delayed run to fill the small peripheral vassals to exclude subsegmental embolism and be shore your patients will understanding your breathe hold instruction to avoid motion artifact which degraded the image quality false +ve result.
