Radiation does not stay in the body with a CT scan: After a CT scan, no radiation remains in the body. On the contrary, a small amount of radiation may stay in the body for a short time after a PET scan. PET scans detect cancer earlier than other tests: Unlike other forms of imagi...
Methods Fifty-one consecutive patients underwent 53 restaging PET–CT scans with a concurrent diagnostic quality CT scan. Two body imaging radiologists independently assessed the CT's; each then teamed with a nuclear medicine specialist to review the PET–CT's. Two teams conferred for consensus on...
对此,八一医院医学影像科主任吴建伟也表达了自己的看法,PET-CT的射线对身体确实会造成伤害,积累到一定程度会有致癌风险,所以不建议正常人把PET-CT作为常规体检,只有真正有需要的才会去做PET-CT检查的,没有需要的不要去凑热闹。 对此,我们应该听从医生的建议! 做体检应该从常规检查做起,尽管这些检查不可能全面兼顾,...

PET-CT was performed either before neoajuvant or adjuvant chemotherapy for final clinical staging. Median age was 68 years (47-87), 87% (41) were men. 41 patients (87%) had bladder cancer, 5 an upper urinary tract tumor (10%) and 1 patient had a cancer of the urethra (2%). ...
PET/CT适宜人群 一、肿瘤高危人群 有肿瘤家族聚集现象者,还有就是接触高危因素的人群,如有烟酒嗜好、经常接触有毒有害物质者等。 二、有癌前病变的人群 癌前病变如肝炎、肝硬化、胃溃疡、直肠息肉、宫颈炎等极易在不知不觉中转化为恶性肿瘤,定期做PET/CT检查有助于...
肺鳞状细胞癌(squamous cell lung cancer,SCC):起源于肺支气管粘膜的鳞状上皮的恶性肿瘤,病理上包括角化型、非角化型和基底细胞样型。大约占原发性肺癌的30%,和吸烟史密切相关,可能超过95%的肺鳞癌是吸烟者,50岁以上男性多见,男性中98%的鳞癌≧50岁,小于45岁男性和女性患者诊断鳞癌要特别慎重,多原发鳞癌实际上...
研究中用于靶向放射性摄取阳性病灶的方法包括认知融合(4项研究)、PET/CT引导下的靶向活检(1项研究)、PET/MRI 靶向活检(1项研究)、PET/CT 融合(2项研究)和PET /超声融合(1项研究)。1 项研究未提及详细靶向方法。所有10篇文献均以靶向...
