Definitive diagnosis of hepatic hemangiomas: MR imaging versus Tc-99m-labeled red blood cell SPECT.

Abstract: Thirty-seven patients with 69 suspected hemangiomas found by means of computed tomography (CT) and/or ultrasound were studied with both 0.5-T magnetic resonance (MR) imaging and single photon emission CT (SPECT) with technetium-99m-labeled red blood cells. Using a criterion of "perfusion-blood pool mismatch," SPECT readers diagnosed 50 of 64 hemangiomas and all five "nonhemangiomas" (sensitivity, 78% [95% confidence interval, 0.664 - 0.864]; accuracy, 80% [0.69 - 0.877]). Qualitative analysis of lesion signal … Show more

“…The results of MRI in present study, although obtained only in 8 patients with haemangioma are in accordance with other previous report [20] the use of other invasive imaging methods, such as scientigraphy and technetium-99 m labeled red blood cell scanning, has also been reported for the diagnosis of benign liver lesions especially haemangiomas [20]. The risk of needle induced bleeding during ultrasographic or CT guided biopsy in benign hpervascular tumors is reported to be low (0.03% -0.04%) [17].…”

“…For similar size lesions, MRI sensitivity varies from 85% to 100%. For lesions less than two cm, sensitivity of RBC scintigraphy is 58% and accuracy 60% and MRI carries a sensitivity of 83% and an accuracy of 84% (7). As MRI often fails to differentiate hemangioma from hypervascular neoplasm or focal nodular heperplasia, blood pool imaging with SPECT is considered the method of choice for confirmation of hemangioma.…”

“…Charakteristisch ist der Speicherdefekt im Kolloidszintigramm sowie die verzögerte Anreicherung und das diskordante Blutfluss/Blutspeicher-Verhältnis im 99m Tc-Blutpoolszintigramm. Die Sensitivität wird mit 70-90 % angegeben, kann aber durch Anwendung einer single photon emission tomography (SPECT) auf über 90 %, auch für Hämangiome < 3 cm, gesteigert werden [30,31] und bietet somit in den Händen erfahrener Untersucher eine außer-ordentlich hohe diagnostische Treffsicherheit.…”

“…In zahlreichen kontrollierten Studien ist gezeigt worden, dass die MRT mittlerweile mit einer Sensitivität von über 90 % und der höchsten Spezifität von über 95 % allen anderen bildgebenden Verfahren überlegen ist [31,32]. Insbesondere die hohe Signalintensität bei T 2 -gewichteter Darstellung lässt ein Leberhämangiom als scharf begrenzte Läsion gut erkennen ("light bulb"-Phänomen).…”
