Age-Dependent Small-Animal Internal Radiation Dosimetry

Molecular Imaging, 2013
Rats at various ages were observed to present with different radiosensitivity and bioavailability for radiotracers commonly used in preclinical research. We evaluated the effect of age-induced changes in body weight on radiation dose calculations.

First-in-man evaluation of 124I-PGN650: A PET tracer for detecting phosphatidylserine as a biomarker of the solid tumor microenvironment [PDF]

, 2017
Purpose: PGN650 is a F(ab′) 2 antibody fragment that targets phosphatidylserine (PS), a marker normally absent that becomes exposed on tumor cells and tumor vasculature in response to oxidative stress and increases in response to therapy.

Internal computational dosimetry of natural cisplatin activated in neutron flux

Brazilian Journal of Radiation Sciences, 2022
Cisplatin is currently used in the treatment of numerous types of tumors, such as head and neck, esophagus, bladder, testicle. However, the cisplatin use is limited due to its cytotoxic effects.

Dosimetric validation of a magnetic resonance image gated radiotherapy system using a motion phantom and radiochromic film. [PDF]

, 2017
PurposeMagnetic resonance image (MRI) guided radiotherapy enables gating directly on the target position. We present an evaluation of an MRI-guided radiotherapy system's gating performance using an MRI-compatible respiratory motion phantom and ...

Specific absorbed fractions of internal photon and electron emitters in a human voxel-based phantom: A monte carlo study

World Journal of Nuclear Medicine, 2017
The specific absorbed fraction (SAF) of energy is an essential element of internal dose assessment. Here reported a set of SAFs calculated for selected organs of a human voxel-based phantom.

Radiological Loco-Regional Treatments for Cholangiocarcinoma: A Systematic Review of the Literature. [PDF]

Liver Int
ABSTRACT Cholangiocarcinoma (CCA) is the second most common primary liver cancer and is being diagnosed with increasing frequency worldwide. We performed a systematic review on radiofrequency (RFA), microwave (MWA), irreversible electroporation (IRE), trans‐arterial chemoembolization (TACE) and selective internal radiation therapy (SIRT) in CCA.

Using microelectrode models for real time cell-culture monitoring [PDF]

, 2011
This paper proposes a cell-microelectrode model for cell biometry applications, based on the area overlap as main parameter. The model can be applied to cell size identification, cell count, and their extension to cell growth and dosimetry protocols ...
