“…Patients' position within the machine was supine with head first. Scans were obtained from supra-diaphragmatic level to below symphysis pubis with automated tube current modulation (mA); 120 kVp; pitch 1.3 (Atta et al, 2016) Quantitative fat analysis Based on non-contrast MSCT of abdomen, studies were acquired from the local PACS system and 3D synapse workstation employing 3D fat analysis software (synapse, Fujifilm) ( Figure 2). Starting analysis just above diaphragm and reaching down to level of symphysis pubis (Ohshima et al, 2008).…”

Background: Substantial evidence has supported the association between adipocytokines and many types of cancers. However, the results in the setting of colorectal cancer (CRC) remain conflicting. Aim: This study aims to evaluate the predictive power of adipocytokines (Leptin and Resistin) levels and abdominal fat distribution in the diagnosis of colorectal cancer. Methods: Eighty participants were recruited then divided into three groups based on endoscopic and histopathological examination; 30 patients with colon cancer, 25 with colonic adenoma, and 25 controls. Serum adipocytokines (Leptin and Resistin) levels were measured, and the quantitative fat analysis was calculated based on an abdominal CT scan. Results: Multivariable logistic regression revealed that two predictors (leptin and Resistin) of CRC development could be used. Visceral/superficial fat rate was the most significant predictor among the parameters of quantitative fat analysis. Also, psoas muscle and visceral fat volume showed non-significant differences among the study groups. Conclusion: For the diagnosis of colorectal cancer, Leptin and Resistin were valuable independent predictors, while quantitative fat analysis parameters failed to be; the most important of these parameters in prediction was Visceral/superficial fat rate.

“…However, combining information from both axial and coronal images may be needed, especially for the lower ureter obscured by bowel loops or iliac vessels (Figure 6). Curved planar re-formated images have been utilised to provide images mimicking a contrast-enhanced study and improve diagnostic yield for ureteric lesions [40]. UVJ stones could be diferentiated from vesical stones by prone CT of the bladder area (Figure 7).…”

Non-contrast computed tomography (CT) abdomen has emerged as a irst line investigation in suspected upper urinary tract obstruction. Underlying causes can usually be ascertained on computed tomography of kidneys, ureters and bladder (CT KUB). However, further investigations may be required to delineate/conirm underlying pathology like ureteropelvic junction obstruction (UPJ), diferentiation between obstruction and residual dilatation. Actual protocol of CT KUB for evaluation of stone disease and haematuria vary on institutional guidelines. CT KUB is not only extremely sensitive and speciic in the diagnosis of stone; it is now used in the pre-operative nomograms in predicting success of various endourological interventions like percutaneous nephrolithotomy (PCNL) and shock wave lithotripsy (SWL). Determination of stone density, stone volume, stone composition, skin to stone distance, presence of ureteral wall oedema, perinephric oedema are highly predictive of stone free rate. CT recognition of various anomalies, presence of retro-renal colon, horse-shoe kidney, malrotation, etc. can help in beter planning to avoid complications. One of the major limitations of CT is the radiation dose, besides cost and availability. Modiication in technique and technological innovation has resulted in signiicant dose reduction from 4.5 to about 1 mSv.
