Gastric carcinoma: imaging diagnosis, staging and assessment of treatment response.

摘要: Gastric carcinoma (GC) is one of the most common causes cancer-related death worldwide. Surgical resection only cure available and dependent on GC stage at presentation, which incorporates depth tumor invasion, extent lymph node distant metastases. Accurate preoperative staging therefore essential for optimal surgical management with consideration and/or postoperative chemotherapy. Multidetector computed tomography (MDCT) its ability to assess depth, nodal disease metastases preferred technique GC. Endoscopic ultrasonography more accurate assessing wall invasion in early cancer, but limited assessment advanced local or stenotic cancer detection Magnetic resonance imaging (MRI), although useful staging, not proven be effective. Positron emission (PET) detecting characterizing Both MDCT PET are treatment response following chemotherapy recurrence after resection. This review article discusses usefulness modalities detecting, potential role newer applications including CT volumetry, virtual gastroscopy perfusion
