Results: In 2007, we provided 602 SPET/CT services in myocardial perfusion scan for attenuation correction and 202 SPET/CT services in other scans for image fusion. Among 64 regional bone SPET/CT services, we noted 2 (3.13%) significant motion artifacts and 2 (3.13%) streak artifacts induced by beam hardening effect while among 25 Ga-67 local SPET/CT services. According to the features including low tube currents and slow rotating speed of this SPET/CT, some problems such as the patient safety, longer scan time, alignment mismatch and radiation protection would be analyzed and discussed.

结果：2007年804例SPET/CT造影中，602例心肌血流灌注断层摄影进行衰减校正，共202例病例进行影像融合，其中鎝－99m-MDP局部SPET/CT发生「影像上明显可见的移动假影」的比例为3.13%(2/64)，镓－67局部SPET/CT发生移动假影的比钊则为24%(6/25)，因射束硬化效应所造成的条状假影有产生干扰融合影像判读的情形，其他问题包括SPET/CT之CT低管球电压及低转速之机器特性、受检者的安全、较长的造影时间、对位错误及辐射防护筝。

After unenhanced ct scans were obtained, mdctde were performed after intravenous injection of contrast with a rate of 4 ml/s, successive scan for 45 s, subsequently scan at 65, 85, 105, 125, 145, 165, 185 and 205 s.

平扫后，以4 ml/s的速度静脉注入对比剂进行动态增强扫描，连续扫描45 s后，每20 s扫描一次至205 s。

Results With the low-dose scan, The sensitivity and accuracy rates of the detection of nephrolithiasis and ureterolithiasis on the low-dose scan were 100% and 98% respectively.

Apparent different thermal behaviors between micro-PS and o-PS were observed during DSC scan: micro-PS displayed an irregular exotherm aboveglass transition and an exotherm of about 6.4 J/g at around 157 ℃ during the firstscan, and only one glass transition similar to o-PS was shown in the subsequent scan.

具体表现为两者在热行为方面的差异：第一次DSC扫描过程中，micro-PS出现两个放热峰，第一个不规则且与玻璃化转变重叠，第二个在157 ℃；而第二次DSC扫描则仅表现出与o-PS一样的玻璃化转变。

Each case was studied by CT scan at 1, 3, 6 and 12 months after the procedure. Results DSA features of all 9 cases were the same as those of enhanced CT/MRI scan. Lipiodol aggraded in the foci dispersedly.

栓塞后4天开始行经皮经肝瘤体内穿刺多点注射博莱霉素8~16mg ，间隔3~4天再次注射，连续2~3次，1月后复查 CT ，以后3、6个月及1年不定期复查 CT 。

Methods 11 cases with cavernous sinus cavernous angiomas were all proved by operation and pathology, 11 cases were examined all by MRI plan scan and enhancement scan, 5 cases were examined by CT.
