To assess differences between four different voxel-based dosimetry methods (VBDM) for tumor, liver, and lung absorbed doses following (90)Y microsphere selective internal radiation therapy (SIRT) based on (90)Y bremsstrahlung SPECT/CT, a secondary objective was to estimate the sensitivity of liver and lung absorbed doses due to differences in organ segmentation near the liver-lung interface.

Internal dosimetry is of critical importance to obtain an accurate absorbed dose-response relationship during preclinical molecular imaging and targeted radionuclide therapy (TRT). Conventionally, abs...
Lu-PSMA-617 enables targeted delivery of beta-particle radiation to prostate cancer. We determined its radiation dosimetry and relationships to pre-therapeutic imaging and outcomes. 30 patients with ...
This work seeks to investigate new methods to determine the absorbed dose to water from kilovoltage x-rays. Current methods are based on measurements in-air and rely on correction factors in order to ...
A relatively high signal for choline-containing compounds (total choline, tCho) is commonly found in H MR spectra of malignant tumors, but it is unclear if this also occurs in tumors in the liver. We...
Y-microsphere radioembolization or selective internal radiation therapy is increasingly being used as a treatment option for tumors that are not candidates for surgery and external beam radiation ther...
This is a pilot study with the primary aim being to identify the minimum number of scans and measurements necessary to determine accurately the absorbed radiation doses delivered from inte...
In this study, peptide receptor radionuclide therapy (PRRT) with 177Lu-Octreotate (LuTate) will be personalized, i.e. administered activity of LuTate will be tailored for each patient to m...
Fatty liver in the obese is a common finding; some cases develop steato-hepatosis which in the long-term can lead to liver cirrhosis. The effect of bariatric surgery on fat distribution in...
study target is assessment of the accuracy of linear measurement obtained from CBCT images on 3D volumetric rendering and multiplanar slices with different voxel sizes
By improved kidney dosimetry including biological effective dose and taking into account potential risk factors (especially for kidney toxicity), it might be possible to give an optimal an...
A procedure to measure the amount of radiation absorbed by the body during RADIOTHERAPY by DOSIMETERS in the patient’s skin or natural cavities.
Experimentally induced tumors of the LIVER.
Tumors or cancer of the LIVER.
A class of natural contraceptive methods in which SEXUAL ABSTINENCE is practiced a few days before and after the estimated day of ovulation, during the fertile phase. Methods for determining the fertile period or OVULATION DETECTION are based on various physiological indicators, such as circulating hormones, changes in cervical mucus (CERVIX MUCUS), and the basal body temperature.
A group of transmissible viral diseases of chickens and turkeys. Liver tumors are found in most forms, but tumors can be found elsewhere.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
