Abstract

ABSTRACT

Background: Osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. In the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. In this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ILP) for treatment of osteoid osteoma in Iranian patients.

Materials and Methods: In this case series study, we evaluated 9 known cases of osteoid osteoma that were referred for ILP from orthopedic section of Imam Khomeini hospital during 2001 and 2002. Diagnosis was confirmed by plain X-ray, CT, isotope & MR scan. ILP was done by interventional radiologists of medical imaging center. Percutaneous ILP was performed by Nd-Yag laser, using 400-1000 joules energy (according to nidus size) and adjusting on 2 watts power.

Results: The procedure was successful in all patients. We had pain relief in 24 hours. Follow up from 5 months to one year showed no recurrence.

Conclusion: The procedure is a safe and effective method for patients and could be applied for proper cases.

Abstract

Background: The purpose of this study is to estimate PSD indirectly using a Radiation Dose Structured Report (RDSR) from Cath lab interventional procedures. The estimated dose was then compared with direct measurements using films. Materials and Methods: Information on radiation exposure and dosage associated with a specific interventional radiology procedure is provided in the RDSR document. The RDSR produced by the machine was verified using slab phantom, Gafchromic XRV3 film, and Ray Safe X2 detector. The PSD is estimated by adding the intensely projected beam dose in acquisition mode with the fluoroscopic dose percentage obtained from the RDSR. During the procedure, Gafchromic films were used to measure PSD directly. Then, the estimated PSD was compared with the measured PSD. Result: The PSDmes and PSDcal in this study showed an average difference of 0.12 Gy (8%). The Wilcoxon Signed-Rank test has a p-value of 0.08 and the Spearman's rank correlation coefficient (rs) of 0.97 indicates a very strong positive correlation between the two variables. Conclusion: The Statistical analysis shows that the estimation of PSD using RDSR is reliable for monitoring the patient. This method may help the cardiologist to follow up of the patients to give extra care to skin reactions. A safe standard work practice will certainly monitor the prevention of undesirable consequences of radiation.
