Nakamura looked at contrast-enhanced ultrasonographic findings in three dogs with insulinomas… what did they find about the enhancement pattern?
That they vary.
Vaquero et al: Traditional and novel vertebral ratios on Great Danes with and without wobblers, How was the new ratio measured?
IN the VD image
The distance between articular process joint vs vertebral body width (A/B)
Vaquero et al: Traditional and novel vertebral ratios on Great Danes with and without wobblers, the VD ratio was significant;y associated with what?
Spinal cord compression
Vaquero et al: Traditional and novel vertebral ratios on Great Danes with and without wobblers, The VD ratios was significantly smaller in affected GDs at what disc space?
C5-C6 and C6-C7
Vaquero et al: Traditional and novel vertebral ratios on Great Danes with and without wobblers, for each 0.1 unit increase in the VD ratio value there was a what % decrease in the odds of spinal cord compression being present REGARDLESS OF THE SITE?
65% decrease.
- 00 = 0.01 probability of compression
- 4 ration = 0.91 probability of compression
What is the difference betwen the intravertebral ratio vs intervertebral ratio when looking at cervical spondylomyopathy?
Intravertebral ratio– defined as the minimum in-travertebral sagittal diameter divided by the correspond-ing vertebral body height
Intervertebral ratio– defined as the minimum inter-vertebral sagittal diameter divided by the correspondingvertebral body height.
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, what ratios were more accurate, caudal lungs or cranial lungs?
Cranial when a receiver operating characteristic curve was produced
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, what ratio in the cranial lungs was found to have a 77% sensitivity and 100% specificity for predicting chronic bronchitits?
>0.6
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, what lungs were significantly greater in the ratio, caudal or cranial?
Cranial
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, was there a significance when hemithoraxes, weight of patient, age, image thickness or CT machine used was looked at?
NO
What is the sensitivity of thoracic radiographs diagnosising chronic bronchitits?
65%
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, what was the PPV and NPV of the cutoff of 0.6?
100% PPV
95% NPV
Szabo et al: CT bronchial wall to pulmonary artery diatmeter ratio in dogs, what lung lobes are considered most accurate?
Cranial.. Caudal is too small and all were under the 0.6 ratio even the affected.
What is the BA ratio cut off for bronchectasis in a cat?
0.9 ratio
Paragonimiasis is commonly seen in what lobes?
Caudal lungs
What is the common radiographic finding of paragonimous?
Multiloculated pneumatocysts in dogs (pic)
Ill-defined interstitial nodular densities in cats
Parzefell et al: MRI of CNS neosporosis: Most common characteristic of neospora?
****Bilateral and symmetrical cerebellar atrophy.
Spinal cord intramedullary lesions
Multifocal brain lesions (grey and white mater)
Parzefell et al: MRI of CNS neosporosis: Is transmitted how and is what kind of parasite?
Transmitted transplacentally
Obligate intracellular protozoan
Hart et al: US of the outer medulla in normal dogs: What size of dogs had the highest frequency of hyperechoic outer medulla?
<5kg
Younger dogs
Dogs >40kg did not have it at all.
Hart et al: US of the outer medulla in normal dogs: What is the conclusion of this study?
Hyperechoic appearance of the outer medulla in the kidneys can be normal appearance
Levine et al: Contrast fluoroscopy in dysphagic cats: What were the most common abnormalities noted in dysphagic cats?
- Hiatal hernia
- Esophageal strictures
- Esophageal dysmotility
ESOPHAGEAL PROBLEMS
No cricopharyngeal or oropharyngeal dysphagia noted.
Kutara et al: Triple phase CTA for hepatic masses: What were the characteristics of hepatocellular carcinomas? Nodular hyperplasia? Mets?
HCC - Heterogenous pattern with any contrast enhancement
Nodular hyperplasia - Homogenous pattern hyper to isoattenuating
Mets - Homogeneous and hypoattentuating
So you can tell the difference s they say.
Fina et al: CT characteristics of eosinophilic pulmonary granulomatosis in dogs: What age groups were these dogs? What infectious disease should be tested for?
Young <5yo
Large breed dogs
Heartworm
Fina et al: CT characteristics of eosinophilic pulmonary granulomatosis in dogs: What type of CT characteristics are seen?
Smoothly marginated, heterogeneous pulmonary mass
HONEYCOMB-LIKE enhancement pattern.
CAUDAL LUNG LOBES
