The goal of this review is to assess the importance of various imaging modalities which can be used in assessing the viability and integrity of the bone allograft. As it is widely in use in majority of major and minor reconstructive procedures. Show less

Introduction Multislice computed tomography examinations performed 3 to 4 days after the onset of symptoms is the imaging procedure of choice in acute pancreatitis, which is mainly done for evaluating the complications. Due to radiation exposure and cost, alternative scoring systems like Ranson’s score and Glasgow’s score were devised but were cumbersome. The serum amylase and lipase were found to increase with progression of disease. The objective of this study was to evaluate the association of acute pancreatitis by modified CT scoring system with the serum levels of amylase and lipase. Material and Methods In hundred patients presenting with acute pancreatitis, the severity of pancreatitis was recorded using the modified CT severity index. The serum amylase and lipase levels were recorded and correlated with modified CT severity index score. Results Among 100 patients studied, 46%, 40% and 14% had mild, moderate and severe grades of pancreatitis respectively by modified CTSI score. No significant correlation was found between the levels of serum amylase (r = -0.104, p = 0.301) and lipase (r = -0.177, p = 0.079) with the modified CT severity index in patients with acute pancreatitis. Conclusion The serum level of amylase and lipase had non-significant correlation with the modified CT severity index score and thus did not indicate severity of pancreatitis. Show less

Attenuation differences from 2 x-ray sources allow differentiation and characterization of stone types with similar radiation dose compared to single-energy CT scan. The difference is shown in colours, allowing preoperative prediction and management of stones. We determined the effect of DECT-KUB on urological management of patients with uric acid stones since it was first introduced in our centre. 50 patients with uric acid stones were selected from 2 year groups, each with 25 patients and their urological managements were reviewed retrospectively. We concluded that DECT-KUB is an accurate way of determining the chemical characteristics of renal calculi and can alter patients’ management. It has gained wide acceptance among clinicians in our centre and is now widely used to plan urological management of patients with renal calculi. Based on urological management comparison of patients who presented in the year 2011 with uric acid stones and patients in the year 2020, we concluded that patients with uric acid stones based on DECT-KUB findings can start dissolution therapy instead of surgical extraction or lithotripsy prior to biochemical analysis results become available. Although utility of DECT-KUB is widely accepted among clinicians in our centre it may not be available worldwide and this is the limiting factor in its universal use. Show less
