Multidetector computed tomography (MDCT) is a widely used cross-sectional imaging modality for initial evaluation of patients with suspected pancreatic ductal adenocarcinoma (PDAC). However, diagnosis of PDAC can be challenging due to numerous pitfalls associated with image acquisition and interpretation, including technical factors, imaging features, and cognitive errors. Accurate diagnosis requires familiarity with these pitfalls, as these can be minimized using systematic strategies. Suboptimal acquisition protocols and other technical errors such as motion artifacts and incomplete anatomical coverage increase the risk of misdiagnosis. Interpretation of images can be challenging due to intrinsic tumor features (including small and isoenhancing masses, exophytic masses, subtle pancreatic duct irregularities, and diffuse tumor infiltration), presence of coexisting pathology (including chronic pancreatitis and intraductal papillary mucinous neoplasm), mimickers of PDAC (including focal fatty infiltration and focal pancreatitis), distracting findings, and satisfaction of search. Awareness of pitfalls associated with the diagnosis of PDAC along with the strategies to avoid them will help radiologists to minimize technical and interpretation errors. Cognizance and mitigation of these errors can lead to earlier PDAC diagnosis and ultimately improve patient prognosis.

胰腺癌MDCT的陷阱：减少错误的策略。

多探测器计算机断层扫描（MDCT）是广泛用于诊断可疑胰管腺癌（PDAC）的患者的断层成像方法。但是，由于与图像获取和解释相关的许多陷阱，包括技术因素，成像特征和认知错误，PDAC的诊断可能具有挑战性。准确的诊断需要熟悉这些陷阱，因为可以使用系统策略将这些陷阱降到最低。次优的采集方案和其他技术错误（例如运动伪影和不完整的解剖覆盖）会增加误诊的风险。由于固有的肿瘤特征（包括小的和等增强的肿块，外生性肿块，细微的胰管不规则和弥漫性肿瘤浸润），图像的解释可能具有挑战性，并存的病理情况（包括慢性胰腺炎和导管内乳头状黏液性肿瘤），PDAC的模仿者（包括局灶性脂肪浸润和局灶性胰腺炎），分散注意力的结果以及对搜索的满意程度。认识到与PDAC诊断有关的陷阱以及避免这些陷阱的策略，将有助于放射科医生将技术和解释错误降到最低。对这些错误的认识和缓解可以导致PDAC的早期诊断并最终改善患者的预后。认识到与PDAC诊断有关的陷阱以及避免这些陷阱的策略，将有助于放射科医生将技术和解释错误降到最低。对这些错误的认识和缓解可以导致PDAC的早期诊断并最终改善患者的预后。认识到与PDAC诊断有关的陷阱以及避免这些陷阱的策略，将有助于放射科医生将技术和解释错误降到最低。对这些错误的认识和缓解可以导致PDAC的早期诊断并最终改善患者的预后。
