Medical Image Diagnostic Value of Computed Tomography for Bladder Tumors

Abstract

Objective. To study computed tomography (CT) imaging characteristics of bladder tumors, to explore the value of CT in tumor diagnosis, and to identify the relevant factors of CT missed diagnosis so that medical staff can be more accurate in the diagnosis of bladder tumors. Methods. To retrospectively analyze the CT manifestations of 153 bladder tumor cases confirmed by paraffin pathology in our hospital and to study the difference between the benign and CT imaging features. CT indicators mainly include the number, location, morphology, calcification, bladder wall smoothness, CT value, degree of enhancement, and invasion of surrounding tissues and organs. Then, we retrospectively analyze 17 cases of CT missed diagnosis of bladder tumors, analyze related factors, and discuss the role of CT in the diagnosis of bladder tumors. Results. This study has shown that with the help of CT images, the diagnosis rate of bladder tumors has been greatly improved. Of the 153 patients studied, noninvasive urothelial carcinoma accounted for 18.95% of all benign and malignant bladder tumors, invasive urothelial carcinoma accounted for 67.93%, prostatic metastatic carcinoma and inflammatory myofibroblastoma accounted for 8.47%, pheochromocytoma accounted for 1.31%, inverted papilloma accounted for 1.31%, tubular choriocarcinoma accounted for 0.63%, and endocystitis accounted for 1.31%. In addition, the blood supply level, CT index bladder wall smoothness, and CT value are also statistically significant ( P < 0.05 ). Conclusions. CT is of high value in the diagnosis of bladder tumors, and benign and malignant bladder tumors have CT and CT imaging features. The size of bladder tumors is related to the missed diagnosis rate of CT. The application of CT examination technology can improve the accuracy of diagnosis of bladder tumors.

Quantitative differentiation of non-invasive bladder urothelial carcinoma and inverted papilloma based on CT urography

“…This may be attributed to their biological behavior. The tumor cells of BUC grow at different rates in all directions, resulting in irregular or lobulated tumor shapes, which promotes the precipitation and adsorption of urate crystals around the focus [ 16 ]. Moreover, about 25% of BUC infiltrates downward into the muscular layer, causing thickening and stiffening of the basal bladder wall, while the adjacent normal bladder wall was soft and mobile, creating a junction bulge or disruption of continuity [ 17 ].…”

Relapse and Survival in Bladder Cancer Patients Undergoing microRNA-129 and microRNA-145 Assays

“…CT helps in determining the localization of tumors [47]. CT displays BC diagnostics, tumor stage, and therapeutic selection vascular structure.…”

Clinical Observation of Transurethral and Suprapubic Laser Therapy for Superficial Bladder Tumors

“…Three consecutive measurements are taken to obtain the maximum urine flow rate. Post-void residual urine volume is measured using a color Doppler ultrasound diagnostic instrument to measure the volume of urine in the patient's bladder, from which the residual urine volume is calculated; ⑤ Incidence of postoperative complications: it includes difficulty urinating, bladder perforation, and postoperative bleeding [10][11][12].…”

“…Before treatment, the levels of various tumor markers of the two groups of patients were compared (P > 0.05), and after treatment, the levels of various tumor markers of the patients in the observation group were lower than those of the control group (P < 0.05), see Table 2 [11].…”
