“…As a result, their reported sensitivity was 100% concluding suspicion of malignancy raised by CT usually warrants further investigation [9]. A recently published article with a retrospective design and larger sample size of 717 calculated an overall sensitivity of 74.5% of routine CT detecting CRC and correlated an improved sensitivity with an increase in lesion size [11]. A slightly greater sensitivity compared to our prospective diagnoses; however, lesion size on pathology was not taken into account in our study.…”

“…Planning, CT is being used for pre-operative assessment of the growth and involvement of adjacent structures, including the fat and pelvis muscles. [16][17][18] In a study, the percentage of carcinoma of the colon was 60%. The accuracy of detection of CRC in poorly prepared bowel on CT is documented to have an accuracy of approx.…”

Objectives: To determine the diagnostic accuracy of multi detector computed tomography (MDCT) in detecting mesorectal fascia involvement in colorectal carcinoma, taking histopathology as a gold standard. Study Design: Cross-sectional study. Place and Duration of Study: Department of Radiology, Combined Military Hospital Quetta from Jun to Dec 2019. Methodology: A total of 117 suspected patients of colorectal carcinoma, aged 40-80 years of either gender were included. All the patients underwent MDCT and then were looked for mesorectal fascia involvement. After surgical intervention, the his to pathological result of respected specimens was correlated with MDCT findings. Results: MDCT showed mesorectal fascia involvement in 66 (56.41%) patients. Histopathology confirmed mesorectal fascia involvement in 62 (52.99%) cases, whereas 55 (47.01%) patients revealed no mesorectal fascia involvement. In MDCT positive patients, 56 patients were true positive, while ten patients were false positive. Among 51 MDCT negative patients, 6 were false-negative while 45 were true negative. Overall results of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of MDCT in detecting mesorectal fascia involvement, taking histopathology as the gold standard was, 90.32%, 81.82%, 84.85%, 88.24% and 86.32% respectively. Conclusion: This study concluded that MDCT is a recommended modality due to its high sensitivity. It is an accurate modality for pre-operative detecting mesorectal fascia involvement in colorectal carcinoma patients.

“…As part of presurgical planning, CT is used to assess the tumor and involvement of adjacent structures such as fat and pelvic side walls including pelvic musculature. [29][30][31] One study determined that the percentage of colon carcinoma was 60%, and the accuracy of detecting CRC in unprepared bowel on CT was assessed to be 80%, with sensitivities of 75%-100% and specificities of 86%-96%. 32…”

Objective: To determine diagnostic accuracy of Profusion Computed tomography (PCT) for diagnosis of colorectal carcinoma (CRC) taking histopathology as gold standard. Study Design: Descriptive, Cross-sectional. Setting: Department of Radiology, Allied Hospital Faisalabad. Period: 10th March 2022 to 9th September 2022. Material & Methods: A total of 451 patients with colorectal cancer suspicion and ages 50-80 years of either gender were included in the study. Patients having severe renal disease, preoperative radiation therapy or chemotherapy, no surgical intervention after CT, contrast media contraindication, pathologically benign colorectal mass, and tumor depth less than 2 cm based on CT were not included. Pre-operative perfusion CTs was performed on all patients. Dynamic perfusion CTs were performed for 65 seconds following intravenous administration of contrast media, and blood flow (BF) and blood volume (BV) in the tumor were assessed. The surgical specimens were forwarded to the hospital's pathology laboratory, where the presence of CRC was labeled according to operational definitions. CT perfusion was performed in radiology department and results of PCT were compared with that of histopathology. Results: Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of Profusion Computed tomography (PCT) in diagnosing colorectal carcinoma (CRC) with histopathology being gold standard was 90.26%, 88.59%, 91.98%, 86.24% and 89.58% respectively. Conclusion: This study concludes that Profusion Computed tomography (PCT) is a highly sensitive and accurate modality for the diagnosis of colorectal carcinoma.
