CT sensitivity was highest for triphasic and quadriphasic examinations compared to single phase or biphasic protocols ( P = 0.03). Most studies were at high risk of bias. Data Conclusion MRI is more sensitive than CT for pancreatic cancer liver metastases detection, accounting for confounding ...
Automatic segmentation of the liver and hepatic lesions is an important step towards deriving quantitative biomarkers for accurate clinical diagnosis and computer-aided decision support systems. This paper presents a method to automatically segment liver and lesions in CT and MRI abdomen images using casc...
图1. 患者治疗前腹部 CT 平扫及增强扫描:A 为腹部 CT 平扫,肝脏右叶可见囊实性包块,大小约 11.5 cm × 12.6 cm×11.2 cm;B 为腹部 CT 增强扫描,可见部分囊壁及分隔不均匀强化;C 为 PET-CT,肝右叶分割状囊实性病变,大小约 11.8 cm...
MRI scan vs. CT Both tests let a doctor see inside your body to diagnose a condition or how you're responding to a treatment. Both procedures require you to lie on a table and go inside a circular scanner while a technician goes into another room to take the images. But the tests hav...
针对慢性乙型肝炎(CHB)合并脂肪变性患者的评价,有研究[41]通过比较肝/脾CT值(CTL/S)、FibroScan (CAP)和MRI-PDFF三种测定方法的差值,证明MRI-PDFF具有较好的可重复性及稳定性。CTL/S值与MRI-PDFF显著负相关,而CAP值与MRI-PDFF显著正相关。表明MRI-PDFF与CTL/S、CAP之间具有一定的一致性。联合应用MRI-PDFF...
CT of the chest is frequently used to further study an abnormality on a plain chest X-ray. It is also often used to look for enlarged lymph nodes. Abdominal and pelvic CT looks at the abdominal and pelvic organs (such as the liver, spleen, kidneys, pancreas, and adrenal glands) and th...
本例患者肝脏病灶 CT 显示囊壁为弧形强化,并且有典型的「 囊内囊 」和「 蜂房征 」;MRI 呈长 T1、长 T2 为主混杂信号包块影,内部可见多发线样、条片状等 T1、等 T2 信号分隔影;导致影像诊断为肝包虫病。该患者有牧区旅游史,但无喜食生肉、与牧区牛羊等密切接触等,血清 IgG-ELISA 和 IgM 抗体均为阴性,...

然而,因残留肝组织储备功能不足引起的肝切除术后肝衰竭(posthepatectomy liver failure,PHLF)是肝癌患者术后最主要的死亡原因[3]。因此,术前预测术后残留肝组织储备功能对于改善患者的预后至关重要。当前,肝肿瘤术前主要通过血清生化指...
CT scan is recommended to detect potentially resectable metastatic lesions, primarily in the lung and the liver (Figure 1) [4,8]. Moreover, CT can detect extraluminal recurrence non-evident on endoscopy. However, due to its low soft-tissue contrast, CT is limited in evaluating local tumor ...
