METHOD OF NMR IMAGING USING ANTIBODY TO CARDIAC MYOSIN
COLLIMATOR SYSTEM WITH IMPROVED IMAGING SENSITIVITY

Smith assigned to
A collimator system rotatable about an axis of rotation for use in a radionuclide emission tomography camera for imaging a region of an object, including a collimator having a number of collimator elements for restricting and collimating the radionuclide emissions. The collimator elements are disposed with their axes intersecting at least one line, parallel to the axis of rotation, at at least two different angles. The collimator elements establish a selected variation in imaging sensitivity across the imaging region.
An in vivo NMR imaging method comprising administering to a human patient an NMR contrast agent comprising a specific affinity organic substituent complexed with a paramagnetic substance and subjecting the patient to NMR imaging.

MULTIPLE DIAGNOSABLE DISTANCE RANGE ULTRASONIC DIAGNOSTIC APPARATUS
PARAM.AGNETIC CONTRAST AGENTS FOR MR IMAGING

First and second ultrasonic transducers are provided at the distal end portion of a flexible insertion portion (to serve as a probe) of an endoscope. During diagnosis, the distal end portion of insertion portion is fixed in a tubular organ by a balloon which is filled with water. Ultrasonic lenses having different focal distances are mounted on the transducers. The resonance frequencies of the transducers differ from each other. The transducers are rotated about a shaft of the insertion portion by a motor, in order to mechanically radial-scan an object to be ex-
In the NMR imaging of a subject comprising administering to such subject a composition containing an ima.ge-modifying effective amount of an image enhancer, permitting the enhancer to move through the subject, and after a time interval taking an NMR image of the subject, the improvement which comprises employing as said enhancer a complex of a paramagnetic polyvalent metal and a partial amide and/or ester of diethylenetriaminepentaacetic acid. The complexes are new. I
