- Synthetic Approach to 99mTc-labeled SPECT Radiotracers with Multi-nitroimidazoles for Hypoxia
Hypoxia, defined as the deficiency of oxygen, is a significant hallmark of cancers presenting in the majority of solid tumors. Detection of tumor hypoxia is essential in cancer diagnosis to prevent cancer progression, metastasis, and resistance to cancer therapies in clinical......
- Incidentally detected abnormal finding of femoral bone density image due to treatment of postoperative lymphatic leakage
Bone Mineral Densitometry (BMD) values is determined numerically with T or Z-score while the image is not considered in the interpretation. Abnormal finding was observed in the left femoral bone density image of a 64-year-old female patient who underwent a left kidney......
- Incidentally detected abnormal finding of femoral bone mineral densitometry due to paraffin injections for buttock augmentation
Bone mineral densitometry (BMD) is an important tool for diagnosing osteoporosis and osteopenia. However, as confirmed by several studies, imaging also serves as a significant tool in providing additional information about the patient. Therefore, radiotechnologists......
- The Effect of Contrast Agent on the Change of Hepatic Uptake of 99mTc-Mebrofenin in Patients with Liver Transplantation
Purpose: 99mTc-mebrofenin hepatobiliary scintigraphy (HBS) is an important and clinically useful diagnostic imaging study for detecting complications after liver transplantation. CT contrast agents due to their high atomic numbers, lead to a decrease in gamma ray count......
- Satisfaction survey on music listening in patient waiting areas and hallways
Purpose: Music therapy helps alleviate anxiety, depression, and pain for cancer patients, contributing to stress relief. With such advantages, music therapy is applied across a broad spectrum of treatment areas, including mental disorders, developmental......
- The feasibility of algorithm for iterative metal artifact reduction (iMAR) using customized 3D printing phantom based on the SiPM PET/CT scanner
Purpose: To improve the image quality in positron emission tomography (PET), the attenuation correction technique based on the computed tomography (CT) data is important process. However, the artifact is caused by metal material during PET/CT scan, and the image quality......
- Consideration of the Usefulness of 18F-FET Brain PET/CT in Brain Tumor Diagnosis
Purpose: 18F-FET, a radiopharmaceutical based on a Tyrosine amino acid derivative using the Sodium-Potassium Pump-independent Transporter (System L) for non-invasive evaluation of primary, recurrent, and metastatic brain tumors, exhibits distinct characteristics. Unlike the widely......
- Evaluating the Usability of Medical Body Wrap in Whole Body Bone Scan
Purpose: When performing nuclear medicine examinations, body wraps or plastic supports are used to support and immobilize the patient's upper extremities to prevent patient safety accidents. However, the existing plastic supports compromised patient and staff safety,......
- A Study on the Tracking of Count-Based Volumetric Changes in Nuclear Medicine Imaging
Purpose: Quantitative analysis through count measurement in nuclear medicine planar images is limited by analysis techniques that are useful for obtaining various clinical information or by organ overlap or artifacts in actual clinical practice. On the other hand, the use of SPECT......
- Image Comparative Evaluation by PET/CT Equipment Using Phantom
Purpose: This study aims to identify SUV, SNR, spatial resolution, and axial uniformity under the same reconstruction conditions and to find out the differences between equipment models. Materials and Methods: The equipment was GE's Discovery 600, 710, IQ, MI(GE Healthcare, USA),......
- A Study on the Comparison of One Step Method and Two Step Method to Improve Reporting of CA 19-9 Results
Purpose: CA 19-9 is the most widely used tumor marker for the diagnosis of digestive system tumor, especially pancreatic and biliary tract cancer. This study was conducted to improve the result value near reference range by comparing the reagents of CA 19-9 one step method......
