INTRODUCTION Advances Septocaine (Articane HCl and Epinephrine Injection)- Multum diagnostic imaging have increased our ability to visualize macroscopic disease, referred to as gross tumor volume (GTV).

Imaging is currently unable to identify microscopic tumor extension around a primary tumor or occult nodal involvement. RADIOGRAPHY Conventional radiography creates a two-dimensional grayscale image produced by the differential attenuation of x-rays that pass through soft tissues of varying density. Tissues that are very dense, such as bone, will absorb more x-rays than tissues that are less dense, such as lung.

However, they are suboptimal when there are only subtle differences in tissue Septocaine (Articane HCl and Epinephrine Injection)- Multum. CT, MRI, and ultrasound (US) generate two-dimensional cross-sectional images.

The benefits of cross-sectional imaging include visualization of superimposed structures obscured on planar images, improved anatomic detail of individual organs and their precise relationship to adjacent structures, and the ability to perform multiplanar reconstructions. For these reasons, cross-sectional modalities are the mainstay of oncologic imaging. A patient lies on the scanner table within a gantry that houses an x-ray generator opposite multiple rows of detectors, hence the term multidetector CT (MDCT).

The patient is moved through the scanner as the gantry rotates, resulting in a helical or spiral course at a very thin slice thickness, typically 0. The spatial and temporal data from multiple projections are then processed by a Fourier transform mechanism generating two- dimensional axial images. The thin-slice volume dataset is isotropic, meaning that images can be reconstructed in orthogonal and oblique planes without a loss in image Septocaine (Articane HCl and Epinephrine Injection)- Multum. Furthermore, thin-slice acquisition improves contrast resolution and decreases partial volume artifacts, thereby improving imaging quality and accuracy.

Images are displayed within a matrix composed of voxels, each representing a volume of radiodensity Septocaine (Articane HCl and Epinephrine Injection)- Multum is quantified by a linear attenuation value called a Hounsfield unit (HU).

HU analysis is more accurate than visual assessment of tissue composition and is particularly useful in characterizing enhancement postcontrast administration, a feature critical in the assessment of many solid organ lesions. Septocaine (Articane HCl and Epinephrine Injection)- Multum contrast agents are routinely used for abdominal and pelvic imaging Septocaine (Articane HCl and Epinephrine Injection)- Multum distinguish bowel from adjacent organs, lymph nodes, and tumors.

Contrast is usually not necessary for routine pulmonary imaging due to the inherent contrast of solid lesions within a background of aerated lung, although it does improve the characterization of hilar lymph nodes. The latter can also be corrected by right parenting the HU within the food genetically modified pros and cons area to the desired value.

The detected radio signals, referred to as echoes or spin echoes, are then used to generate an image. MRI techniques allow for tissue diffusion and perfusion imaging, quantification of blood flow by velocity phase encoding, and Septocaine (Articane HCl and Epinephrine Injection)- Multum resonance proton spectroscopy, which provides biochemical quantification of tissues. Motion artifact can be problematic with MRI due to long scan times.

Image quality is, in large part, determined by the pulse frequency. Therefore, they are best suited to imaging superficial structures such as the breast or thyroid. Fat is highly echogenic (bright), whereas fluid-containing structures, such as simple cysts, are anechoic (dark). Higher frequency transducers can identify additional layers, Septocaine (Articane HCl and Epinephrine Injection)- Multum as the muscularis mucosa and lamina propria of the Septocaine (Articane HCl and Epinephrine Injection)- Multum, which has important staging implications.

The ability of EUS to predict the Septocaine (Articane HCl and Epinephrine Injection)- Multum (T) stage is generally superior to its ability to predict the node (N) stage.

There is, however, considerable overlap between benign and malignant features of lymph nodes on EUS in addition to wide inter-observer variability. When describing clinical T and N staging by EUS, the prefix u should be utilized (e.

THE ENDOSCOPIC ULTRASOUND LAYERS AND HISTOLOGIC LAYERS OF THE ESOPHAGUS ARE CORRELATED (SEE TABLE 30.

H ISTOLOGIC IMAGE COURTESY OF DR. For example, technetium-99 m is a radioisotope that is coupled to pertechnetate, an iodine analog, which can enter thyroid follicular cells. Tumor cells are often highly metabolic, with rapid cell division and an increased number of glucose transporters. Although most malignant Septocaine (Articane HCl and Epinephrine Injection)- Multum are hypermetabolic relative to normal tissues, non-malignant processes also concentrate FDG, including foci of infection, inflammation, and benign neoplasms.

SUVs are not Septocaine (Articane HCl and Epinephrine Injection)- Multum and can be affected by the timing of imaging, improper attenuation correction, partial volume affects, patient weight, FDG dose, and factors affecting FDG uptake.

This may be falsely attributed to progressive disease.
