Biograph Vision™ PET/CT nuclear medicine scanner. Empowers you to redefine PET/CT imaging with precision-driven performance.
PET/CT显像中的CT扫描一般采用低剂量(低毫安)扫描模式。有研究针对18F-FDG PET/CT检查所受有效剂量进行测量分析,CT扫描采用低剂量参数,结果发现,PET所致有效剂量的中位数为3.69mSv,CT所致有效剂量中位数为4.93mSv。低剂量PET的应用,导致CT在整体PET/CT...
PET Scans Are a Vital Part of Cancer Care The majority of PET scans are performed for diagnosing, staging and evaluating treatments for cancer care. A PET scan helps the physician distinguish between living and dead tissue or between benign and malignant disorders, unlike other imaging technologies...

PET/CT scanners offer a hardware solution for aligning and viewing functional and anatomic images that is immune to many of the errors in strictly software registration techniques. Moreover, PET attenuation-corrected emission scans benefit from the use of the onboard CT for fast, low-noise attenua...
All patients had no clinical signs suggestive of distant metastases, and underwent preoperative screening computed tomography (CT) and positron emission tomography (PET)/CT scans. Of 100 patients without lymphadenopathy, 17 patients were suspected of having nodal metastasis in CT and PET/CT, but ...
CT血管造影、CT灌注成像、图形质量更高的多层螺旋CT、快速全身检查的petCT等,极大拓展了CT的应用天地。 CT与X射线,掀起了一场疾病诊断革命,医生可以无创伤地获取患者体内的病变信息,外科医生可以在手术前得到明确的诊断。 恶性肿瘤、皮肤溃烂、掉牙、脱发…… 最初研究X线的科学家们毫无防护,频繁大剂量全身接触射线后...
