The Linear No Threshold Model (LNT) defines that cancer occurrence due to radiation exposure exhibits linearity without a threshold. Many research results have confirmed the clear linearity of radiation exposure and cancer risk at high doses. However, controversy exists at low doses (<100 mSv) and low dose rates (<0.1 mSv/min, <5 mSv/hour) intervals. Within the low dose range of 100 mSv ......

Purpose: In this study, we investigated whether extravasation could be predicted by measuring the dose rate once at the injection site before PET/CT scanning. Materials and Methods: The dose rate at the injection site was measured for 412 patients, and the severity of extravasation was evaluated ......

Purpose: Patients receiving high doses of radioactive isotopes for thyroid cancer treatment often require hospitalization due to high external radiation exposure. Meals are provided, leading to food waste generation, which is sometimes managed using food waste disposers. Given that shredded food waste is ......

Purpose: Our institution, the demand for [13N]ammonia is increasing, so we will introduce the manufacturing process, quality testing, and other processes for [13N]ammonia injection until it is supplied to patients. Materials and Methods: [13N]ammonia is produced by irradiating water containing 5 mmol of ......

Purpose: The pulmonary ventilation/perfusion scan is used to detect pulmonary embolism before transplantation and to evaluate lung function after transplantation. Pulmonary scans can be performed using two methods: 2D planar imaging and 3D SPECT. In the case of 2D imaging, there are inherent ......

Purpose: It is important for liver transplant patients to maintain a certain level of hepatitis B antibodies to prevent recurrence of hepatitis B after liver transplant surgery. The liver transplant and hepatobiliary surgery department at our hospital uses hepatitis B surface antibody titer testing as an important ......
