Hawkeye SPECT仪融合图像用于脑脊液鼻漏诊断和定位

Objective The purpose of this study was to evaluate the clinical value of the 99Tcm-DTPA cerebrospinal fluid (CSF) Hawkeye SPECT fusion imaging for diagnosing and localizing CSF rhinorrhea (CSFR). Methods Thirty-three patients with suspected CSFR were included in this study. All cases un-derwent planar and SPECT and CT imaging at 120 and 180 min, respectively, after 99Tcm-DTPA injection via lumbar puncture before surgery treatment. The location and path of CSF leakage were diagnosed on pla-nar and SPECT fusion imaging. SAS 6.12 software was used to analyze both sets of imaging data, and the χ2 test was used to compare the results from planar imaging with those of SPECT fusion imaging. Results In 33 patients with CSFR, 31 abnormally concentrated radionuclide activity and location of leakage were foun-ded on SPECT fusion imaging, whereas 30 of such abnormalities were detected by planar imaging. All CSFR cases were confirmed by surgery afterwards. The sensitivity and accuracy for diagnosing and localizing CSFR were 93.9% (31/33), 90.9% (30/33) in SPECT fusion imaging and 93.5% (29/31), 78.3% (18/23) in planar imaging. Conclusion 99Tcm-DTPA CSF Hawkeye SPECT fusion imaging is an efficient, simple and accurate method for diagnosing and localizing CSF leakage.

SPECT/CT显像在股骨头颈或转子区病变鉴别诊断中的应用

Objective The study was aimed to evaluate the value of SPECT/CT in assessment of femoral foci of abnormal bone metabolism classified as indeterminate on bone scanning using 99Tcm-methylene diphosphonate(MDP).Methods There were 94 patients with solitary femoral abnormal uptake in bone scanning included.SPECT was accompanied by inline CT over the femoral region.All of the images were blindly interpreted independently by two experienced board-certified radiologists.The reference standard was follow-up over half a year of MRI,CT,SPECT,or pathology.Diagnoses which consist with reference were counted as accurate.Diagnoses which either not consist with reference or undetermined were counted as false.McNemar test was used for data analysis.Results of the 94 patients,78 patients(male 42,female 36,mean age 62 years) had definite diagnosis;19 were malignant and 59 were benign diseases.The diagnostic accuracy by bone SPECT,bone CT was significantly lower than fusion imaging[58.9%(46/78),87.2%(68/78),96.2%(75/78),respectively,X2=16.48,48.18,both P＜0.05].Conclusions Most of the solitary femoral foei caused by benign diseases.SPECT/CT using 99Tcm-MDP has additional value than with SPECT or CT alone in differentiating malignancy from benignancy in femoral foci.     

Study of age of fusion of hyoid bone

The present study was conducted to determine the age of fusion of greater cornua with the body of hyoid bone. Age of fusion of hyoid bone can help in determining the age of an individual, especially of unknown dead bodies where only skeletal remains are available. A victim of compression of neck will more likely have fracture of hyoid bone if his hyoid bone is fused. Indian authors have reported that the fusion of hyoid bone occurs after 40 years of age. Studies done by foreign workers observed that hyoid bone fused at an earlier age (30-40 years). A total of 170 excised hyoid bones from dead bodies belonging to the age group of 20-65 years were studied. Fusion occurred earlier in females as compared to males by about 5 years. The mean age of unilateral and bilateral fusion in males was 38.25 and 53.16 years, respectively. The mean age of unilateral and bilateral fusion in females was 38.00 and 48.50 years, respectively. All the hyoid bones were fused after the age of 60 years. No significant differences were found between the fusion on right and left side.

延迟性脾破裂误漏诊原因分析

目的探讨延迟性脾破裂误漏诊原因和预防措施.方法回顾性分析总结12例延迟性脾破裂中的诊断和误漏诊的经验与教训.结果本组延迟性脾破裂的误漏诊5例(41.66%).对多发伤与脾破裂并存可能认识不足,外伤史轻微或伤员隐瞒外伤史,缺乏腹痛-缓解-突然再腹痛的典型病史,缺乏“对冲性脾破裂”力学分析和整体化诊断思路等为其误漏诊的主要原因.结论详细的外伤史和全面系统检查,重视腹以外多发伤掩盖腹内脏器伤及延迟性脾破裂可能.确立外伤-腹内脏器伤-脾破裂整体化诊断思路.不间断地辅以B超检查脾形态学变化和腹内有无积液,腹腔穿刺确定有无血腹、X线胸腹部检查观察左侧胸肋角和膈肌运动情况、必要时CT检查以尽早发现脾包膜下血肿,降低延迟性脾破裂误漏诊率.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

The value of information of duration of pregnancy in establishment of paternity

Summary In order to get an idea of the value of the information on the duration of pregnancy in establishment of paternity, 511 records from 17 lower courts in Sweden were studied.It was found that when a blood group investigation has been performed, only a small number of cases remain where the paternity claim should be rejected by a court of law for the reason that the period of pregnancy has been extremely long or short.It was shown that only very extreme probability values (percentages) should give reason for rejection of paternity claims if a larger risk of error is to be avoided. The risk is somewhat smaller with long pregnancies than with short ones.The results of this study emphasize the difficulties involved in probability assessment in paternity suits.This report was presented at the Seventh International Medical-Legal Seminar, Stockholm 1971.
