| dc.description.abstract | [EN]Aim To evaluate the value of 99mTc-MIBI double-phase scintigraphy (DPS) and early SPECT/CT in the pre-surgical assessment of patients with primary hyperparathyroidism (PHPT). Also, to calculate the correlation between uptake and some biological parameters. Material and methods Forty patients with PHPT were included: 37 solitary adenomas, 1 hyperplasia, and 2 double adenomas. Fifteen patients had ectopic glands. DPS and early SPECT/CT were acquired in all patients. Ultrasound was performed in 31/40. All patients underwent surgery, intra-operative iPTH measurements, and histopathological examinations. Qualitative DPS uptake was assessed and correlated to pre-surgical calcium, iPTH levels, gland weight, and maximum diameter. Results In the planar study, there were 23 positive cases, 8 doubtful, and 9 negatives. With the SPECT/CT, 8/9 negatives cases were located. All doubtful cases were confirmed as positives. Gland location improved in 16 cases (12 ectopic). DPS + SPECT/CT failed to detect a solitary adenoma and at least one gland in three cases of multiglandular disease (MGD). The sensitivity by patient was: DPS 72.5%, DPS + SPECT/CT 90%, and ultrasound 42%. Ultrasound and scintigraphy (DPS + SPECT/CT) were concordant in 16/31 patients. For the rest of them, scintigraphy proved correct in 14/15, and both techniques failed in one case. There was a significant correlation between level of uptake and iPTH level, gland weight, and maximum diameter. Conclusion Early SPECT/CT improves sensitivity and the locating of parathyroid pathological glands and increases diagnostic confidence. iPTH level, glandular size, and weight are related to the qualitative assessment of 99mTc-MIBI uptake in early DPS. | en_EN |
| dc.description.abstract | [ES]Objetivo Evaluar la gammagrafía de doble fase con 99mTc-MIBI (GDF) y el SPECT/TC precoz, en la valoración prequirúrgica del hiperparatiroidismo primario (HPTP), calculando la correlación entre grado de captación y algunos parámetros biológicos. Material y métodos Se incluyeron 40 pacientes: 37 adenomas solitarios, dos adenomas dobles, una hiperplasia. Quince tenían glándulas ectópicas. En 40 pacientes se realizaron GDF y SPECT/TC; en 31/40, ecografía. Todos los pacientes fueron intervenidos, realizando determinación de PTHi intraoperatoria y examen histopatológico. Se evaluó cualitativamente la captación en la GDF, correlacionándose con calcio y PTHi prequirúrgicos, peso y diámetro máximo glandulares. Resultados En el estudio planar se obtuvieron 23 casos positivos, 8 dudosos, y 9 negativos. Con SPECT/TC se localizaron 8/9 de los negativos. Todos los dudosos se confirmaron como positivos. La localización glandular mejoró en 16 casos (12 ectópicos). La GDF + SPECT/TC fallaron en la detección de un adenoma solitario y en la visualización de alguna de las glándulas en tres casos de enfermedad multiglandular (EMG). La sensibilidad por pacientes fue: GDF 72,5%, GDF + SPECT/TC 90%, ecografía 42%. Ecografía y gammagrafía (GDF + SPECT/TC) concordaron en 16/31 pacientes. De los no concordantes, la gammagrafía acertó en 14/15 y ambas técnicas fallaron en uno. Hubo correlación significativa entre captación y PTHi, peso y diámetro máximo glandulares. Conclusion El SPECT/TC precoz mejora la sensibilidad y la localización de las paratiroides patológicas y aumenta la confianza diagnóstica. PTHi, tamaño y peso glandulares se correlacionan con la valoración cualitativa de la captación precoz de 99mTc-MIBI en la GDF. | es_ES |
