  2. VQ Scan Pulmonary Embolism

    show more
    Description: Ventilation-perfusion scintigraphy in a woman taking oral contraceptives and valdecoxib. (A) After inhalation of 20.1 mCi of Xenon-133 gas, scintigraphic images were obtained in the posterior projection, showing uniform ventilation to lungs. (B) After intravenous injection of 4.1 mCi of Technetium-99m-labeled macroaggregated albumin, scintigraphic images were obtained, shown here in the posterior projection. This and other views showed decreased activity in the following regions: apical segment of right upper lobe, anterior segment of right upper lobe, superior segment of right lower lobe, posterior basal segment of right lower lobe, anteromedial basal segment of left lower lobe, and lateral basal segment of left lower lobe.

  3. Diagnostic algorithm: Pulmonary embolism

    show more
    Description: A diagnostic algorithm for pulmonary embolism (estimated frequencies of test results and associated prevalences of pulmonary embolism for a hypothetical cohort of 1000 outpatients) [1]. If a very sensitive D-dimer assay is used, it can be the first test performed: a negative result excludes pulmonary embolism regardless of clinical assessment category and a positive test can be followed by a ventilation–perfusion scan [2]. A ventilation–perfusion scan can be performed as the initial test without using clinical assessment of the probability of pulmonary embolism as part of the diagnostic process [3]. Pulmonary angiography or helical CT may be considered if the clinical assessment of pulmonary embolism probability is low, particularly if a D-dimer test has not been done [4]. Additional testing (e.g., helical CT, bilateral venography) may be considered if overall assessment suggests a high probability of pulmonary embolism (e.g., 50%–80%), symptoms are severe or cardiopulmonary reserve is poor [5]. Venography should be considered if there is an increased risk of a false-positive ultrasound result (e.g., previous venous thromboembolism, equivocal ultrasound findings, preceding findings suggest low probability of pulmonary embolism [e.g., ≤ 10%]) [6]. It is reasonable not to repeat ultrasound testing, or to do only 1 more ultrasound after 1 week, if preceding findings suggest a low probability of pulmonary embolism (e.g., ≤ 10%) [7]. If helical CT is used in place of ventilation–perfusion lung scanning: (i) intraluminal filling defects in segmental or larger pulmonary arteries are generally diagnostic for pulmonary embolism; (ii) all other findings (i.e., a normal CT scan or intraluminal filling defects confined to the subsegmental pulmonary arteries) are nondiagnostic and can be managed as shown for a nondiagnostic lung scan.

  6. Retinas, Normal

    show more
    Description: Retinas - Normal Retina is the innermost of the three tunics of the eye, surrounding the vitreous body and continuous posteriorly with the optic nerve. The retina is composed of light-sensitive neurons arranged in three layers; the first layer is made up of rods and cones and the other two transmit impulses from the rods and cones to the optic nerve. The rods are sensitive in dim light, and the cones are sensitive in bright light and are responsible for color vision.

  7. Temporal Wasting - Adult Male

    show more
    Description: Temporal Wasting - Adult Male with HIV Patients with wasting syndrome show severe loss of temporal muscle mass and cheek tessues. Loss of facial fat and premature greying, thinning, and fall of hair contribute to rapid ageing apparence which is a striking feature in patients with AIDS

  8. Tympanic Membranes, Normal

    show more
    Description: Tympanic membranes - normal Tympanic membrane a thin, semitransparent membrane, nearly oval in shape, that stretches across the ear canal and separates the tympanum (middle ear) from the external acoustic meatus (outer ear); called also eardrum. It is composed of fibrous tissue, covered with skin on the outside and mucous membrane on the inside. It is constructed so that it can vibrate freely with audible sound waves that travel inward from outside. The handle of the malleus of the middle ear is attached to the center of the membrane and receives the vibrations it collects, transmitting them to the other ossicles of the middle ear (the incus and stapes), which in turn transmit the vibrations to the fluid of the inner ear.
