Heart scintigraphy

Myocard scintigraphy is used to appraise the perfusion of the myocardal muscle. It provides information on any constrictions which may exist in the cardiovascular system with a typical stored image of the myocardal muscle of the left ventricle.

This enables, for example, proper perfusion of the myocardal muscle to be proven when it is at rest. When a load is placed on the heart, a narrowing of the cardiovascular system means that less blood flows through the myocardal muscle of a particular region. This is shown in the image by accumulation under load which is less than when at rest.

The examination is conducted with a load being placed on the heart (ergometry) under the control of a doctor and, if necessary, also when at rest. For this purpose the gamma camera is used to produce sectional views of the heart from three perspectives (short axis, vertical and horizontal long axes).

Preparatory measures

  • You must fast for at least 4 hours before the examination.
  • Certain medicines must be discontinued (this must be discussed beforehand with the doctor providing the treatment).
  • Comfortable clothing makes sense.

Heart scintigraphy

Constriction in the coronary vessels. Normal distribution of activity at rest. Under stress reduced activity in the storage area of ​​the rear and side wall. (see arrow) Thus, exercise-induced reduced blood flow (ischemia) in a coronary artery stenosis in the rear and side wall.

Preparatory measures
