GENERAL RADIOLOGY
Computed Tomography
Fig. 2.1 Patient motion artifact. Axial CT image shows blurring of anatomical structures with apparent duplication of the nasal bones, mimicking fractures Some scanner models use overscan mode for axial…
Bone Mineral Density and Quantitative Imaging
Fig. 6.1 Correct execution of DXA scans: (a) lumbar spine, (b) hip, (c) total body Another common site for BMD measurement by DXA is the hip. This is because the…
Vascular System
Fig. 14.1 Axial contrast-enhanced CT image shows that streak artifacts due to contrast material in the superior vena cava can mimic dissection of the ascending aorta Fig. 14.2 Axial contrast-enhanced…
Nuclear Medicine Imaging
Fig. 4.1 A 65-year-old man with esophageal carcinoma. Tc-99m diphosphonate bone scintiscans done for staging show abnormal soft tissue visualization of the stomach as well as the thyroid gland, consistent…
Interventional Radiology Techniques
Fig. 5.1 (a) Left brachiobasilic fistulogram shows antegrade contrast injection and a stenosis in the proximal basilic vein (arrow). (b) Following angioplasty, diffuse spasm is seen in the midportion of…

Monte Carlo Simulation for an Optical Microscope
(3.1) where N(d) is the number of the unscattered photons at depth d, and N(0) is the number of incident photons [3]. For a given number of photons incident to…
Multiphoton Fluorescence Imaging
(8.1) where α 2p is a 2p fluorescence coefficient, and I 2p and I ex are, respectively, the intensity of the incident and the fluorescence light at the focal region….
