摘要
目的评价CT增强延时扫描对膀胱良恶性病变诊断与鉴别诊断的应用价值。方法32例经临床或病理证实的膀胱良、恶性病变患者均行螺旋CT普通扫描和增强扫描,其中20例于延时5min～15min又经增强延时扫描。结果CT普通扫描显示所有病例膀胱的良、恶性病变。然而,CT增强延时扫描不仅显示普通扫描所见,而且更清晰显示病变的形态、大小、范围、表面受累,以及CT普通扫描未发现的一些细小病灶,诸如2例膀胱壁轻度增厚(<3mm),1例左侧输尿管开口处细长结节灶,以及4例前列腺增生导致膀胱腔内结节的中央沟。结论CT增强延时扫描在膀胱良恶性病变的诊断与鉴别诊断中具有重要的应用价值。
Objective To assess the usefulness of enhanced and delayed CT in the diagnosis and the differential diagnosis of benign and malignant bladder's diseases.Methods Thirty- two patients with clinically or pathologically proved bladder diseases (26 malignant lesions and 6 benign lesions) underwent plain spiral CT and enhanced CT scans,of them ,20 patients underwent additional delayed enhanced CT scans at 5 min～ 15 min after injection of contrast medium.Results Plain spiral CT revealed the malignant and benign lesions of the bladder in all patients.Enhanced and delayed CT scan not only showed what have been presented on the plain CT scans but also more clearly revealed the lesion's shape,size,extent ,surface involvement and some small lesions to be not visible on plain CT scans such as slight thickening of bladder walls(< 3mm)in 2 cases,thin long nodular lesions on left ureter aperture in 1 case,and nodular central canale within bladder cavities due to the proliferation of the prostate in 4 cases.Conclusion Enhanced and delayed CT scan plays an importemt role in the diagnosis and the differential diagnosis of benign and malignant bladder diseases.
