Despite advances in molecular biology, imaging, and treatment, gastric neoplasms remain a significant cause of morbidity and mortality; gastric adenocarcinoma is the fifth most common malignancy and third most common cause of death worldwide (Brenner et al., Methods Mol Biol 472:467-477, 2009; Howson et al. Epidemiol Rev 8:1-27, 1986; Roder, Gastric Cancer 5(Suppl 1):5-11, 2002; Ferlay et al., GLOBOCAN 2012 v1.0, Cancer Incidence and Mortality Worldwide: IARC CancerBase No. 11 [Internet]. International Agency for Research on Cancer, 2013). Because of both the frequency at which malignant gastric tumors occur as well as the worldwide impact, gastric neoplasms remain important lesions to identify and characterize on all imaging modalities. Despite the varied histologies and behaviors of these neoplasms, many have similar imaging features. Nonetheless, the treatment, management, and prognosis of gastric neoplasms vary by pathology, so it is essential for the radiologist to make every effort to differentiate between these lesions and raise the less common entities as differential diagnostic considerations when appropriate.
尽管分子生物学、影像学和治疗方法取得了进展，但胃肿瘤仍然是发病率和死亡率的重要原因；胃腺癌是全球第五大常见恶性肿瘤，也是全球第三大常见死亡原因（Brenner 等人，Methods Mol Biol 472:467-477, 2009；Howson 等人，Epidemiol Rev 8:1-27, 1986；Roder，Gastric Cancer 5(Suppl 1):5-11, 2002；Ferlay 等人，GLOBOCAN 2012 v1.0，Cancer Incidence and Mortality Worldwide：IARC CancerBase No. 11 [互联网]。国际癌症研究机构，2013 年）。由于恶性胃肿瘤的发生频率以及全球的影响，胃肿瘤仍然是所有影像学模式都需要识别和特征化的重要病变。尽管这些肿瘤的组织学和行为多种多样，但许多都具有相似的影像学特征。尽管如此，胃肿瘤的治疗、管理和预后因病理学而异，因此放射科医生必须尽力区分这些病变，并在适当的时候将不太常见的实体作为鉴别诊断的考虑因素提出。
