Diatrizoate distribution volume (DDV) is a property of living tissue which characterizes the distribution of diatrizoate contrast material within the tissue. This study compiles DDV and enhancement data from computed tomography (CT) of normal human adults. Tissues examined include liver, spleen, muscle, fat, and renal cortex. Four abnormal tissues, a cirrhotic liver, a liver infiltrated with metastatic colon carcinoma, and two examples of renal malignant lymphoma, were used for comparison. Time-DDV and time-enhancement values were generated for the normal tissues after a bolus of intravenous diatrizoate. The CT-DDV appears to be a potentially reliable indicator of diffuse organ pathology.
泛影葡胺分布容积（DDV）是活体组织的一种特性，它表征了泛影葡胺造影剂在组织内的分布情况。本研究汇总了正常成年人计算机断层扫描（CT）的DDV和增强数据。所检查的组织包括肝脏、脾脏、肌肉、脂肪和肾皮质。选取了四种异常组织，即肝硬化肝脏、浸润转移性结肠癌的肝脏以及两个肾恶性淋巴瘤实例用于比较。静脉注射一次大剂量泛影葡胺后，得出了正常组织的时间-DDV和时间增强值。CT-DDV似乎是弥漫性器官病变的一个潜在可靠指标。
