What is the ratio of bronchial wall thickness to pulmonary artery diameter on CT images that will give 77% sensitivity and 100% specificity in predicting the presence of chronic bronchitis in the CRANIAL lung lobes in dogs?
>0.6 Radiographs are bad at predicting this (65% sensititve) so trying to make an objective measure.
What could cause abnormal bronchial wall thickness to pulmonary artery diameter on CT images that is not related to bronchial disease?
Pulmonary hypertension -
Echocardiogram is recommended
Measuring wrong
Is getting bronchial wall thickness to pulmonary artery diameter ratios on CT images easy?
No.. ~18% of the time they could not get a ratio
What bronchial wall thickness to pulmonary artery diameter ratio was bigger in dogs on CT… Cranial or caudal lungs?
Cranial
They don’t know why
What is the common features of histiocytic sarcoma in the thorax?
Ventral right middle lung lobe mass
TB and sternal lymphadenopathy
Most common lesion in the abdomen for histiocytic sarcoma?
hypoechoic well-defined nodules in the spleen
Tsukagoshi et al: Decreased gallbladder emptying dogs, What three groups showed decreased gallbladder empyting at 60 min after eating?
Mobile sludge
Immobile sludge
Mucocele
Tsukagoshi et al: Decreased gallbladder emptying dogs, Other than decreased emptying at 60 min what else was seen in dogs with mobile sludge, immobile sludge and mucoceles?
Gallbladder distension
Tsukagoshi et al: Decreased gallbladder emptying dogs, what muscle needs to relax to let bile out?
Sphincter of Oddi
Tsukagoshi et al: Decreased gallbladder emptying dogs, What is the normal emptying ml/kg in a fasting gallbladder on US?
<1ml/kg or >25% total volume within 2 hours
Tsukagoshi et al: Decreased gallbladder emptying dogs, when was postprandial gallbladder volume recorded?
60 and 120 min. No meds were used just fasting and feeding
Tsukagoshi et al: Decreased gallbladder emptying dogs,, how was the volume calculated?
0.52 x L x W x D
Tsukagoshi et al: Decreased gallbladder emptying dogs, How was ejection fraction calculated?
(Volume before - volume after/volume before) x 100.
Tsukagoshi et al: Decreased gallbladder emptying dogs, what was the conclusion with this paper?
Dogs with biliary sludge had diminished gallbladder motor function. The consequence of this is unknown.
Tsukagoshi et al: Decreased gallbladder emptying dogs, was there a significant difference between ejection fraction of immobile sludge and mucocele?
No there was not but there was when comparing mobile sludge to mucoceles.
Tsukagoshi et al: Decreased gallbladder emptying dogs, what modifications to the gallbladder ejection fraction method was made in this paper?
Reducing the number of observation points (just 2) Taking body weight into account in quantity of test meal Excluding erythromycin administration
What two endocrinopathies are associated witih gallbladder mucoceles and lipidemia?
Hypothyroidism
Hyperadrenocorticism
Bruehschwein et al: Contrast-enhanced MRA with PSS, What type of MRA was used in this study to detect PSS?
Contrast-enhanced…. NOT Time of flight
