目的：通过对兔VX2腹膜腔移植瘤的MR影像学表现来评估MR平扫加增强扫描对腹腔内移植瘤的诊断价值。方法采用开腹直接注入瘤粒悬液法制作兔VX2腹膜腔移植瘤模型，接种后第10天对瘤兔腹部进行MR扫描获得影像学结果，以病理结果为金标准评价MR的诊断价值。结果在对＜10mm的腹腔种植瘤进行扫描，MR平扫敏感度为60.19%、准确度55.86%，MR平扫加增强扫描敏感度为78.64%、准确度73.64%，对于病灶检出能力MR增强扫描要优于MR平扫；在对10~20mm之间的腹腔种植瘤进行扫描，MR平扫的敏感度为82.35%、准确度77.78%，MR平扫加增强扫描敏感度91.18%、准确度88.57%，对于病灶检出能力MR增强扫描要明显优于MR平扫；在对＞20mm的腹腔种植瘤进行扫描时MR平扫与MR平扫加增强扫描结果一致，检测能力相同。结论对于＜20mm的病灶MR增强扫描检出能力在敏感度、准确度方面优于MR平扫，而对于＞20mm的病灶MR平扫与平扫加增强检出结果相同均与病理结果一致。
目的：通過對兔VX2腹膜腔移植瘤的MR影像學錶現來評估MR平掃加增彊掃描對腹腔內移植瘤的診斷價值。方法採用開腹直接註入瘤粒懸液法製作兔VX2腹膜腔移植瘤模型，接種後第10天對瘤兔腹部進行MR掃描穫得影像學結果，以病理結果為金標準評價MR的診斷價值。結果在對＜10mm的腹腔種植瘤進行掃描，MR平掃敏感度為60.19%、準確度55.86%，MR平掃加增彊掃描敏感度為78.64%、準確度73.64%，對于病竈檢齣能力MR增彊掃描要優于MR平掃；在對10~20mm之間的腹腔種植瘤進行掃描，MR平掃的敏感度為82.35%、準確度77.78%，MR平掃加增彊掃描敏感度91.18%、準確度88.57%，對于病竈檢齣能力MR增彊掃描要明顯優于MR平掃；在對＞20mm的腹腔種植瘤進行掃描時MR平掃與MR平掃加增彊掃描結果一緻，檢測能力相同。結論對于＜20mm的病竈MR增彊掃描檢齣能力在敏感度、準確度方麵優于MR平掃，而對于＞20mm的病竈MR平掃與平掃加增彊檢齣結果相同均與病理結果一緻。
