изображения с отсроченной визуализацией Explanation: ... -------------------------------------------------- Note added at 36 mins (2016-04-04 12:18:04 GMT) -------------------------------------------------- Surgery of the Thyroid and Parathyroid Glands edited by Daniel Oertli, Robert Udelsman p.443 "another approach referred to us as a sequential (thyroid) washout imaging based on delayed imaging" Campbell-Walsh Urology By Alan J. Wein, Louis R. Kavoussi, Alan W. Partin, Craig A. Peters "15 minute postcontrast density values) of greater than 40% on delayed (washout) imaging, is indicative of adenoma (Fig. 6528)" http://www.google.com/patents/WO1996028190A1?cl=en the value of using an "in- vivo washout" strategy (imaging 24 hours after FIAU administration) to reduce background radioactivity and improve image specificity. delayed imaging - отсроченная визуализация http://www.multitran.ru/c/m.exe?l1=1&l2=2&s=delayed imaging -------------------------------------------------- Note added at 3 hrs (2016-04-04 14:51:11 GMT) -------------------------------------------------- Принцип washout imaging общий - отсрочка получения изображения, а как и на каких анатомических структурах он реализуется - это частный вопрос, которым вряд ли кто-то из участников форума занимался профессионально. По поводу его применения к исследованию легких есть вот такая статья http://jpet.aspetjournals.org/content/337/2/335.full Ventilation/perfusion. An intravenous bolus of 13N-N2-saline provides the opportunity to assess V/Q with PET. Because of the aforementioned low solubility of N2 in blood, virtually all 13N-N2 arriving in the lungs during apnea will diffuse into the alveolar air space in proportion to regional perfusion, thus providing a perfusion map. Subsequent washout imaging highlights tracer retention in poorly ventilated areas. In asthmatic patients at baseline a characteristic vertical perfusion gradient from dorsal to ventral and an almost complete tracer washout was observed. |

изображения в фазе вымывания газа Explanation: http://www.findpatent.ru/patent/132/1321407.html Продолжительность регистрации ... 3 мин в фазе ингаляции ксенона и 3 мин в фазе вымывания газа из легких. http://medical-diss.com/medicina/raschet-funktsionalnoy-osta... СПИСОК СОКРАЩЕНИЙ, ИСПОЛЬЗУЕМЫХ В ДИССЕРТАЦИИ NMB W - Nitrogen Wash-in/Wash-out method - метод вмывания (англ. wash in) /вымывания (англ. wash out) азота http://studopedia.info/9-72994.html - Вентиляционная сцинтиграфия легких с газообразным Хе-133 ”болюсным способом” основана на ингаляционном введении радиоактивного газа с помощью резинового загубника, подключенного к любому спирографу, т.е. для создания замкнутой системы “пациент – спирограф”. Этим методом определяется состояние проходимости трахеобронхиальных путей легких, изучается время заполнения, смешивания и полувыведения газообразного Хе-133 из трахеобронхиального пространства. https://quizlet.com/39074991/nuc-chest-flash-cards/ What agent is this? Xeon 133; 3 phases: initial breath (10sec), equilibrium (2 x 90); washout (3 x 45sec); 220 mrad to lungs Xenon-133 allows for the assessment of all phases of regional ventilation: initial single breath, wash-in, equilibrium, and washout. Single-breath images represent instant ventilation, wash-in and equilibrium images are proportional to aerated lung volume, and washout phases show regional clearance of activity from the lungs and delineate areas of air trapping. |

| Reference: washout images Reference information: The routine view for the ventilation scan is the posterior view. The procedure begins with when the patient is instructed to breathe xenon gas with the facemask firmly in place covering the nose and mouth. The patient takes a deep breath and holds it for 15 seconds. This image is recorded and labeled 15-second inspiration. The patient returns to normal breathing for 60 seconds. At 60 seconds the image is recorded and labeled 60-second equilibrium. Then the patient breathes room air through the mask and three to six images are taken at 60-second intervals until the xenon has been completely exhaled. These are labeled washout images. Xenon gas is not absorbed by the lung and is completely exhaled during the washout phase. The ventilation scan is usually performed first since it does not contribute background radiation to the perfusion scan, but the perfusion scan can contribute background radiation to the ventilation scan. The collected gas is stored in a shielded environment until it returns to background levels. https://www.ceessentials.net/article12.html |
