    • A composition useful as an imaging agent comprises a beta adrenergic receptor antagonist compound, preferably iodopindolol, to which is covalently attached an iodine radioisotope such as .sup.123 I or .sup.124 I. This composition is used in a method for radioimaging beta adrenergic receptors in a tissue, preferably brain. In particular, the method is useful with the radioimaging technique of single photon emission computed tomography (SPECT) or positron emission tomography (PET). The above composition, as well as a kit comprising a set of one or more standard radiographic images of beta adrenergic receptors, are also useful in methods for (1) diagnosing an alteration in beta adrenergic receptors in a tissue, particularly brain; (2) diagnosing suicidal depression in a subject; and (3) detecting the therapeutic normalization of beta adrenergic receptor expression in a subject.
    • 可用作显像剂的组合物包含β-肾上腺素能受体拮抗剂化合物,优选碘吲哚洛尔,其共价连接碘放射性同位素如123I或124I。 该组合物用于放射成像的组织,优选脑中的β肾上腺素能受体的方法。 特别地,该方法对于单光子发射计算机断层摄影(SPECT)或正电子发射断层摄影(PET)的放射成像技术是有用的。 上述组合物以及包含一组或多种β肾上腺素能受体的标准放射照相图像的试剂盒也可用于(1)诊断组织,特别是脑中β肾上腺素能受体的改变的方法中; (2)诊断受试者的自杀性抑郁症; 和(3)检测受试者中β肾上腺素能受体表达的治疗正常化。
