Tomographic Image Reconstruction 1 Introduction
... Tomography is a non-invasive imaging technique allowing for the visualization of the internal structures of an object without the superposition of over- and under-lying structures that usually plagues conventional projection images. For example, in a conventional chest radiograph, the heart, lungs, ...

Optimizing pediatric brain imaging
... At 3.0T, it offers the best compromise between scan time and image contrast. It provides better T1 contrast than SE, TSE, or T1 FFE, and it’s faster than IR-TSE methods. Watch TE and pre-pulse delay when modifying 3D T1 TFE, as these can significantly affect the outcome of brain scans. At 1.5T, fat ...

Nuclear medicine
Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine scans are usually conducted by radiographers. Nuclear medicine, in a sense, is ""radiology done inside out"" or ""endoradiology"" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays.
