Photoacoustic cystography (PAC) has a great potential to map urinary bladders, a radiation sensitive internal organ in pediatric patients, without using any ionizing radiation or toxic contrast agent. Here we demonstrate the use of PAC for mapping urinary bladders with an injection of optical-opaque tracers in rats in vivo.

An Optimized Protocol for the Efficient Radiolabeling of Gold Nanoparticles by Using a ¹²⁵I-labeled Azide Prosthetic Group

Jongho Jeon^1,2, Ha Eun Shim¹, Sajid Mushtaq^1,2, Mi Hee Choi¹, Sang Hyun Park^1,2, Dae Seong Choi¹, Beom-Su Jang^1,2

¹Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute, ²Department of Radiation Biotechnology and Applied Radioisotope Science, University of Science and Technology

A detailed procedure for the synthesis of a ¹²⁵I-labeled azide and the radiolabeling of dibenzocyclooctyne (DBCO)-group-conjugated, 13-nm-sized gold nanoparticles using a copper-free click reaction is described.

We introduce a semi-automatic protocol for shape analysis on brain structures, including image segmentation using open software, and further group-wise shape analysis using an automated modeling package. Here, we demonstrate each step of the 3D shape analysis protocol with hippocampal segmentation from brain MR images.
