It takes 15­20 min based on slice thickness and extent needed and hence needs navigator pulse to track the diaphragm so that images can be acquired only at certain phases of the respiratory cycle 94 medications that can cause glaucoma buy phenytoin with mastercard. The other numbers indicate the following structures: 2 medicine 93832 buy generic phenytoin 100mg on line, left ventricle; 3 medicine ball order phenytoin american express, left atrium; 4 medicine 8 capital rocka purchase phenytoin 100mg amex, right atrium; 5, descending thoracic aorta; 6, pulmonary vein. Its location in the atrial septum and the absence of a perfusion point to a lipomatous septum. The atrial septum is intact and bowing to the right, indicating high right atrial pressure. The descending aorta (behind left atrium) is normal (1: left ventricle; 2: right ventricle; 3: left pleural effusion). The dark area pointed by the arrows is a perfusion defect during firstpass perfusion using Gd chelate. The perfusion defect is seen during vasodilator stress in the lateral wall as well as anterior and inferior walls and completely fills in during rest perfusion. Reversible perfusion defect indicates ischemia and not infarct, and extent indicates multivessel disease. Subendocardial scar indicates an infarct; involvement of inferior septum and inferior wall is consistent with right coronary artery lesion. Scar pattern in myocarditis may be patchy, midmyocardial, subepicardial, or even transmural. Note the heavily trabeculated left ventricle with noncompated to compacted myocardial thickness ratio of >2. The carina is shown well where the trachea branches into the right and left main bronchi. This patient has hypertrophy of his anterior septum and anterior and inferior walls. The upper septum is asymmetrically hypertrophied (arrow) and points more to hypertrophic cardiomyopathy. The short-axis mitral valve view shows a cleft of the anterior mitral valve (arrowed in Figure 6. Both the four- and three-chamber views show transmural scar of the apex with a dark filling defect representing thrombus. The stented segment, which measured 30 mm, is clearly seen on both images in Figure 6. Stress-induced myocardial perfusion defect in the septum, anterior and inferior walls. With vasodilator stress there is lack of perfusion in the septum, anterior and inferior walls (dark areas), representing myocardial ischemia. The contrast-enhanced image of the aorta shows contrast in the true lumen (T), while the false lumen (F) does not enhance. This patient had a type A dissection and underwent ascending aortic repair including a hemiarch. Which of the following imaging procedures is likely to be associated with lowest radiation exposure? Which of the following imaging procedures is likely to be associated with the highest radiation exposure? Patient with a prior myocardial infarction followed by coronary artery bypass grafting D. Spatial and temporal resolution are affected by all of the following except which? Which of the following techniques may be helpful for better coronary visualization for those with calcification? To check for graft patency in a patient with chest pain after prior coronary artery bypass grafting E. There is severe aortic valve calcification and this may increase risk of coronary occlusion C.

Clinical Features the lower lip is the most common site of mucus extravasation phenomenon medicine 2020 discount phenytoin 100 mg on-line, but other sites subjected to trauma may be involved including the buccal mucosa symptoms low potassium discount phenytoin 100 mg amex, anterior-ventral surface of the tongue (location of the mixed serous and mucous glands of Blandin-Nuhn) medicine tablets buy phenytoin 100 mg fast delivery, floor of the mouth medicine identification generic 100 mg phenytoin otc, and retromolar region (Figures 8-2 and 8-3). Lesions are uncommonly found in other intraoral regions where salivary glands are located, probably because of lower susceptibility to trauma. Mucocoeles of the upper lip are very uncommon, a site where salivary gland tumors are more likely. Mucus extravasation phenomenon presents as a relatively painless smooth surfaced mass ranging in size from a few millimeters to 2 cm in diameter. The maximum size is usually reached within several days after injury, and a viscous mucoid material is found if aspiration is attempted. Rather than arising from traumatic duct rupture, this form of mucocele is believed to arise as a result of increased pressure in the outermost part of the excretory duct. These lesions are asymptomatic and numerous, occurring most commonly in the retromolar area, soft palate, and posterior buccal mucosa. Their clinical appearance suggests a vesiculobullous disease, but the lesions persist for an extended time. Histopathology Extravasation of mucin into the connective tissues incites an inflammatory response with neutrophils, macrophages, and granulation tissue forming around the mucin pool (Figure 8-4). The adjacent salivary gland whose duct was transected shows duct dilation, chronic inflammation, acinar degeneration, and interstitial fibrosis. Although a history of a traumatic event followed by development of a bluish translucent mass is characteristic of the mucus extravasation phenomenon, other lesions might be considered when a typical history is absent. These include a Differential Diagnosis · Figure 8-4 · Figure 8-2 Mucus extravasation phenomenon of the lower lip. Mucus extravasation phenomenon showing free mucin (top) surrounded by inflamed granulation and connective tissue and salivary gland tissue. Rarely, a mucocele may appear in the alveolar mucosa of the maxilla or mandible and in this situation an eruption cyst or gingival cyst should be included in the differential diagnosis. Occasionally, periductal scar or an impinging tumor may cause the obstructive sialadenitis. Clinical Features Treatment for the mucus extravasation phenomenon consists of surgical excision. Aspiration of the fluid content provides no lasting clinical benefit because the causative salivary gland will continue to produce saliva. Therefore removal of associated minor salivary glands along with the pooled mucus is necessary to prevent recurrence. No treatment is required for superficial mucoceles because they rupture spontaneously and are short-lived. Mucus Retention Cyst (Obstructive Sialadenitis) Etiology and Pathogenesis Mucus retention cysts usually result from obstruction of salivary flow caused most commonly by a sialolith (Box 8-1). The sialolith(s) may be found anywhere in the ductal system, from the gland parenchyma to the excretory duct orifice. A sialolith (calculus or stone) is the precipitation of calcium salts (predominantly calcium carbonate and calcium phosphate) around a central nidus of cellular debris, inspissated mucin, and/or bacteria. Predisposition includes salivary stasis, chronic sialadenitis, and gout (uric acid Most cases (up to 80%) of obstructive sialadenitis are associated with sialoliths in the submandibular glands (Figures 8-5 and 8-6). About 20% are seen in the parotid glands, and a very small percentage is seen in sublingual and minor glands (especially upper lip). Recurrent swelling and pain are the primary clinical features, with worsening at mealtime. A purulent, cloudy-to-flocculent discharge at the duct orifice when massaged, as well as limited flow from the gland at rest, is a common finding. Mucin in the floor-of-mouth lesions may dissect through the mylohyoid muscle that separates the sublingual from the submandibular space to create a swelling in the neck called a plunging ranula. Mucus retention cysts of the minor salivary glands typically present as asymptomatic swellings without antecedent trauma. Radiographically, nearly 90% of submandibular sialoliths are radiopaque, whereas most parotid stones (90%) are radiolucent. Submandibular gland up to 80%, parotid 20%, sublingual and minor glands 1% to 15% Produce intermittent pain and swelling Sialoliths in minor glands most commonly found in upper lip Typically asymptomatic Stones may be detected by x-ray in major glands. Major glands-remove retention cyst and associated salivary gland, or Remove stone through duct incision, or by massaging stone through duct orifice.
