Abstract: CT was regard as golden standard method for evaluation of blunt abdominal trauma. CT allow good detection of any organ injury and determine its grade upon which the management will be performed. The aim of our study is to evaluate the role of CT in blunt abdominal trauma. This study included 50 patients presented with blunt abdominal trauma. Patients were subjected to clinical history and examination followed by MDCT scan with IV contrast. The results of our study proved that the liver was the most common injured organ representing 40%, spleen 30%, kidney 16%, peritoneum 8%, while the pancreas was the least common one representing only 2% of all our cases .Grade II hepatic injury was the most common representing 65% of patients with hepatic injury, also grade II splenic injury was the most common representing 73% of patients with splenic injury. Both grade I & II renal injuries were the most common each representing 37.5%. In our study 3 cases (6%) were detected having organ injury associated with active bleeding. We conclude that MDCT is the gold standard method for evaluation of blunt abdominal trauma as it play an important role not only in detection of organ injury, but also in the grading of this injury on which the management will be performed. Also it is important in the follow up of cases which undergo conservative treatment. In addition MDCT proved to be highly sensitive in detection of active hemorrhage which is a life threatening condition.

Abstract: AIM: To determine the relationship of body mass index (BMI) on the mean dose length product (DLP) values acquired using modulated (automatic exposure control) and standard computed tomography (CT) scanning protocols as part of a typical 18F-FDG PET/CT study. METHODS: A retrospective study was performed and the dose-length product and BMI values from routine 18F-FDG PET/CT scans of 51 patients were recorded. The scans were performed on a 16-slice PET/CT scanner by using an automatic exposure control (AEC) system. DLP, BMI, age, sex and number of bed positions were documented for each patient. RESULTS: Twenty-four women and 27 men were included in the study (mean age, 52.5 years). The mean BMI was 24.76 kg/m2. The mean modulated DLP was 528.25 mGy/cm. Patients were grouped according to BMI (normal: BMI <25, overweight: BMI 25 – 30, obese: BMI >30) and age (≤18 years, 19 – 59 years, ≥ 60 years). The mean modulated DLP decreased by 22.77% for patients in the normal BMI group (P < 0.001). The obese group of patient’s mean modulated DLP was 26.29% higher (P < 0.01). The DLP decreased by 22.43% for patients aged 60 years and above compared with patients in the 19 – 59 age group. CONCLUSION: The use of modulated scanning protocol significantly reduces the integrated dose received from a whole body CT scan for patients with a BMI < 25. Increasing patient size (BMI >25) significantly increases the integrated dose received. The possible change in body composition with age may also indicate a reduction in dose received from a whole body CT scan using AEC.

Abstract: This study aim to evaluate the role of US and CT when needed in diagnosis of anterior abdominal wall lesions. Ultrasound and Multi-detector computed tomography are currently the study of choice to diagnose abdominal wall lesions; mostly hernia it also allows accurate identification of abdominal wall hernias and their content, and it allows to assess the possible complications, differentiate from other abdominal masses like: tumors, hematoma, abscess and it helps in the detection of pre- or postoperative complications. This prospective study included 50 patients suffering from abdominal wall swelling, US examination of abdomen was performed for all patients and only 10 patients had under gone US and CT examination the abdomen. The ratio of females to males was 28 to 22. Their ages ranged from 22-60 years with mean age of 40 years. Ventral hernia was the most common cause of anterior abdominal wall lesions 26 cases (52%), anterior abdominal lump 14 cases (28%), 10 cases were needed to CT evaluation. Ventral hernia was the most common lesions (30%) 3 cases out of 10 cases, strangulated hernias (20%) 2 cases, spegilan hernia, anterior abdominal wall abscess and desmoid tumor (10%) 1 case for each. US is the prime investigation for patients suspected of having abdominal wall swellings and was the first step in the diagnosis while CT scan was a sensitive tool for imaging and we recommend it as a confirmative imaging method
