Physiologic and anatomic changes following unilateral pubnonary irradiation up to 6,000 rads in dogs were studied. Fractionate irradiation was given to the right lung of 11 dogs divided into three groups which received 2,000, 4,000 and 6,000 rads respectively. Differential bronchospirometry was serially performed at approximately four week intervals for one year. There was no signfficant change...

This paper presents an ontology-based annotation system and BI-RADS (Breast Imaging Reporting and Data System) score reasoning with Semantic Web technologies in mammography. The annotation system is based on the Mammography Annotation Ontology (MAO) where the BI-RADS score reasoning works. However, ontologies are based on crisp logic and they cannot handle uncertainty. Consequently, we propose ...

gamma-Ray sensitivity for cell killing was assayed in 54 human cell strains, including some derived from individuals suffering from certain heritable diseases. The overall range of Do values in this study was 38 to 180 rads, indicating a considerable range of variability in humans. The normal sensitivity was described by a range of Do values of 97 to 180 rads. All ten ataxia telangiectasia cell...

ObjectiveThe present study aimed to evaluate the efficacy of a new two-dimensional shear wave elastography (2D-SWE) method using Siemens ultrasound system and its combination with American College Radiology Thyroid Imaging Reporting Data System (ACR TI-RADS) for differential diagnosis benign malignant thyroid nodules.MethodsConventional images 2D-SWE (E-whole-mean E-stiffest-mean) were prospect...

Breast cancer has the highest incidence among all cancers for women in Taiwan. The current screening policy in Taiwan suggested a biennial mammography for all women 40 to 69 years of age. A recommendation for additional testing is recommended for women with a BI-RADS result of 0 or 4; a request made via postal mail. Approximately 20% of high-risk patients do not receive additional follow-up. Th...

A single high exposure of a person to an irritant chemical by inhalation, typically as an accidental incident involving a gas or vapour, can mean they run the risk of developing a type of asthma called reactive airways dysfunction syndrome or RADS. These people have irritable bronchial tubes and this hypersensitive state may last for some years. In many cases (although not all) it is much more ...

The aim of this study is to compare the current state of lesion identification, the BI-RADS classification and the contrast-enhancement behavior at 7T and 3T breast MRI in the same patient group. Twenty-seven patients with thirty suspicious lesions were selected for this prospective study and underwent both 7T and 3T MRI. All examinations were rated by two radiologists (R1 and R2) independently...

The effect of doses of mixed gamma-neutron radiations or 14 MeV neutrons on the urinary excretion of deoxycytidine (CdR) was evaluated as a biodosimeter in rats. The rats were exposed to doses in the range from 22 to 780 rads. The excretion of CdR in the urine of irradiated rats during the 4to 12-hour postirradiation interval was a function of dose over the range of 22 to 376 radsThis response ...
