Short-term retention of 99mTc activity in bone scintigraphy

Assessment of Patient and Staff Annual Effective Doses at a Nuclear Medicine Department during Bone Scans

“…Table 1 shows the average and diversity of patients' age (years), effective radiation dose (mSv), and administered radiopharmaceutical activity (MBq) per procedure. Whereas the average administered, activity was 750 (440 to 1400) MBq The average administered activity is Previous studies reported the administered activity during bone imaging (MBq) of 99mTc-MDP routinely changes amid 740.0 to 1110.0, with scanning classically executed during two to five hours after intravenous administration of the radiopharmaceutical [8] [9].…”

“…Bone scintigraphy has a vital role in the diagnosis of calcaneus fractures (CF) [16]. The average effective dose per bone scan procedure, according to Ali et al, was 4.2 mSv [8] [9]. The researchers reported that the patient's body weight had no bearing on the given activity.…”

“…Due to the significant amount of given activity, patients were exposed to harmful radiation levels. The practice and patient safety must be improved by establishing operational standards [9]. NM involves handling radioactive substances that can expose staff to radiation both internally and externally as a result of radiopharmaceutical elusions and preparation in specially protected laboratory (hot lab).…”

“…NM involves handling radioactive substances that can expose staff to radiation both internally and externally as a result of radiopharmaceutical elusions and preparation in specially protected laboratory (hot lab). The staff was also exposed to ionizing radiation for the period of administering 99mTc to patients and after the scanning that poses radiogenic hazard for NM personnel [6] [7] [8] [9]. Therefore, depending on workload and procedure approach, areas of the body not covered with the leaded apron might be exposed to unavoidable exposure resulted from ionizing radiation sources.…”
