Echinostoma
|
D004449 |
[A genus of intestinal flukes of the family Echinostomatidae which consists of many species. They occur in man and other vertebrates. The intermediate hosts are frequently mollusks.

Echinostomatidae
|
D004450 |
[A family of flukes (TREMATODA) characterized by a collar of spines at their anterior end. The body is elongated and is covered with spines, and the two suckers are usually close together. (Noble et al., Parasitology: the Biology of Animal Parasites, 6th ed, p183)

Echinostomiasis
|
D004451 |
[Infection by flukes of the genus Echinostoma.

Echium
|
D036661 |
[A plant genus of the family BORAGINACEAE. Members contain GAMMA-LINOLENIC ACID and PYRROLIZIDINE ALKALOIDS.

Echo-Planar Imaging
|
D017352 |
[A type of MAGNETIC RESONANCE IMAGING that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional MRI techniques. It is used in a variety of medical and scientific applications.

|
Echocardiography
|
D004452 |
[Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.

|
Echocardiography, Doppler
|
D015150 |
[Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.
] |
|
Echocardiography, Doppler, Color
|
D018618 |
[Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
] |
|
Echocardiography, Doppler, Pulsed
|
D018619 |
[Echocardiography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
] |
|
Echocardiography, Four-Dimensional
|
D019561 |
[Dynamic three-dimensional echocardiography using the added dimension of time to impart the cinematic perception of motion. (Mayo Clin Proc 1993;68:221-40)
] |
|
Echocardiography, Stress
|
D025401 |
[A method of recording heart motion and internal structures by combining ultrasonic imaging with exercise testing (EXERCISE TEST) or pharmacologic stress.
] |
|
Echocardiography, Three-Dimensional
|
D019560 |
[Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)

|
Echocardiography, Transesophageal
|
D017548 |
[Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.
] |
|
Echoencephalography
|
D004453 |
[Use of reflected ultrasound in the diagnosis of intracranial pathologic processes.
] |
|
Echogenic Bowel
|
D058535 |
[A PRENATAL ULTRASONOGRAPHY finding of excessively dense fetal bowel due to MECONIUM buildup.
] |
|
Echolalia
|
D004454 |
[Involuntary ("parrot-like"), meaningless repetition of a recently heard word, phrase, or song. This condition may be associated with transcortical APHASIA; SCHIZOPHRENIA; or other disorders. (From Adams et al., Principles of Neurology, 6th ed, p485)

|
Echolocation
|
D004455 |
[An auditory orientation mechanism involving the emission of high frequency sounds which are reflected back to the emitter (animal).
] |
|
Echothiophate Iodide
|
D004456 |
[A potent, long-acting cholinesterase inhibitor used as a miotic in the treatment of glaucoma.
] |
|
Echovirus 6, Human
|
D004458 |
[A species of ENTEROVIRUS that has caused outbreaks of aseptic meningitis in children and adults.
] |
|
Echovirus 9
|
D004459 |
[A species of ENTEROVIRUS associated with outbreaks of aseptic meningitis (MENINGITIS, ASEPTIC).
