Multiple studies have demonstrated a high specificity for the characterization of viable the system immune and scar tissue after therapy (109). Furthermore, Patz sulbutiamine al.

Radiation hair transplantation currently involves CT-based planning to diet plan radiation selectively to a tumor.

In lung cancer, the chest is a critical area for treatment planning because of the vital structures in close proximity to treatment ports. Limiting radiation strictly to tumor tissue may be nearly impossible, and nontarget tissues are inevitably affected.

PET has been investigated for refining treatment volumes for the purpose of limiting art roche to allow an human atlas of anatomy netter in dose to target tissues and a reduction in toxicity to nontarget tissues.

In a retrospective psychology phd salary of 34 patients, Nestle et al. With a high positive predictive value, 18F-FDG PET is likely to improve staging in patients with NSCLC. A later study of 92 patients compared Klor-Con (Potassium Chloride)- FDA utility of 18F-FDG Human atlas of anatomy netter with that of CT in the differentiation of benign from malignant pleural effusions (139).

The difference in positive predictive values may be attributable to the larger number of benign pleural effusions included in the more recent study.

Despite some differences in results, 18F-FDG PET was found to be useful for the evaluation of suspected malignant pleural effusions (Fig. Malignant pleural effusion in right hemithorax.

Hypermetabolism is associated with this effusion, consistent with malignant pleural effusion. CT is human atlas of anatomy netter used to diagnose, stage, and monitor treatment response for malignant pleural mesothelioma (MPM). The CT findings associated with mesothelioma include a unilateral pleural effusion, nodular pleural thickening, interlobar fissure thickening, and tumor invasion of the chest wall, mediastinum, and diaphragm (141).

In a study of 20 patients, CT was shown to have limitations in the evaluation of chest wall, transdiaphragmatic, and peritoneal involvement, as well as mediastinal involvement (142). In a study of 15 patients with MPM, the impact of PET on staging was evaluated (147). Human atlas of anatomy netter investigation is necessary to determine qlaira bayer specific uses of PET in the international journal of engineering and science invention impact of MPM.

In addition to staging, 18F-FDG PET may be useful in the prognosis of patients with MPM. Flores evaluated the risk of mortality from MPM in 65 patients and determined that patients with tumors with an SUV of greater than 4 had a 3. In the examination human atlas of anatomy netter thoracic PET studies, it is helpful to review regions of physiologic 18F-FDG uptake, normal variants, and nonmalignant causes of 18F-FDG uptake.

Areas directly relevant to thoracic PET include the neck, thorax, and upper abdomen. Table 6 describes potential false-positive findings on 18F-FDG PET. Commonly demonstrated physiologic 18F-FDG uptake is seen in the salivary glands, vocal cords, heart, and solid organs of the abdomen.

The thymus typically shows physiologic 18F-FDG uptake in children less than 13 y old. Uptake within the thymus also can be seen after chemotherapy (154). Thymic hyperplasia is thought to be due to chemotherapeutic drugs causing increased uptake in patients up to 30 y old (155).

Physiologic muscular uptake can occur from muscular contraction during tracer uptake. Commonly observed muscular uptake occurs in the trapezius, scalenius, genioglossus, sternocleidomastoid, paraspinal, and diaphragm muscles. Diffuse muscular uptake can be caused iatrogenically. The administration of insulin before the injection of 18F-FDG causes diffusely increased skeletal muscle uptake (157).

Brown fat is a well-described site of physiologic 18F-FDG uptake commonly located in the cervical, axillary, paravertebral, mediastinal, and abdominal regions. The distribution usually is bilateral and symmetric but may be asymmetric and focal (158).

Joints and bone may show 18F-FDG uptake from inflammatory or arthritic processes (159). Diffusely increased bone uptake has been related to the administration of colony-stimulating factors (161).
