32-year-old man status post living donor liver transplantation for PSC Postgadolinium arterial phase image (Figure 2.19.1) demonstrates a hepatic artery stump (cutoff) at the level of the anastomosis. A subsequent axial portal venous phase image (Figure 2.19.2) at the level of the porta hepatis shows an absent main portal vein, which is confirmed on the coronal reformatted image (...

Cystic Pancreatic Lesions

Nonfunctioning neuroendocrine tumors (NFET) account for up to 33% of the neuroendocrine tumors of the pancreas, ranging from 1 to20 cmin diameter and showing a higher malignancy rate, up to 90%. The clinical presentation of nonfunctioning neuroendocrine tumors is nonspecific. These tumors, in fact, are predominantly characterized by an expansive growth pattern; therefore, they are clinically silent until adjacent viscera and structures are involved. This makes it difficult to diagnose NFET at an early stage. Correct diagnosis is typically delayed by several years. About 15% of pancreatic NFET are cystic and difficult to differentiation from other cystic pancreatic lesions. In such cases, the important role played by hypervascular rim in the arterial phase image. Literature review and case report оf diagnostics and treatment of Neuroendocrine Tumor with cystic transformation are presented in the article.

32-year-old man with an abnormal left leg, multiple varicose veins, and a history of multiple prior deep vein thromboses and pulmonary emboli Arterial phase (Figure 16.15.1A) and venous phase (Figure 16.15.1B) MIP images from time-resolved 3D MRA with a gadolinium blood pool contrast agent (gadofosveset trisodium [Ablavar]) demonstrate normal arterial anatomy with prominent varicosities posteriorly in the left pelvis and upper thigh on the venous phase image. Pseudostenosis of the common femoral veins bilaterally is likely a subtraction artifact. Axial FSE T2-weighted (...

Bilateral nephroureteral stents are present and can be perceived faintly on the excretory phase image. Note also the right renal cysts and a small filling defect in a left lower pole calyx; this was a small calculus....

High Resolution Electron Micrographs

High resolution electron microscopic study of negatively stained macromolecules and thin sections of tissue embedded in a variety of media are difficult to interpret because of the superimposed phase image granularity. Although all of the information concerning the biological structure of interest may be present in a defocused electron micrograph, the high contrast of large phase image granules produced by the substrate makes it impossible to distinguish the phase ‘points’ from discrete structures of the same dimensions. Theory predicts the findings; however, it does not allow an appreciation of the actual appearance of the image under various conditions. Therefore, though perhaps trivial, training of the cheapest computer produced by mass labor has been undertaken in order to learn to appreciate the factors which affect the appearance of the background in high resolution electron micrographs.
