ABSTRACT
La osificación heterotópica es una condición limitante, que afecta predominantemente a la cadera. Dada su relación con patología postraumática/posquirúrgica, la gammagrafía ósea SPECT/TC resulta de especial utilidad en el diagnóstico diferencial con movilización protésica, aun cuando no hay alteraciones radiológicas. Además, resulta ser una herramienta eficaz para planificación quirúrgica atendiendo al grado de maduración ósea y la posibilidad de fabricar biomodelos mediante impresión 3D.(AU)
Heterotopic ossification is a limiting condition that predominantly affects the hip. Because of its association with post-trau-matic/postoperative pathology, bone SPECT/CT scintigraphy has proven to be especially useful regarding differential diag-nosis involving prosthetic mobilization, even in the absence of radiological abnormalities. Additionally, it is an effective toolfor surgical planning, considering the degree of bone maturation and the possibility of creating biomodels using 3Dprinting.(AU)

AIM: To analyze the sample of pregnant patients who underwent pulmonary perfusion scintigraphy to rule out the pulmonary embolism (PE) suspicion during the acute COVID-19 infection hospitalization period in our hospital. MATERIAL AND METHODS: SPECT scintigraphy with a reduced dose (111 MBq) of 99mTc-macroaggregated albumin was performed in all of the patients (n=5). The obtained images were interpreted by comparing the findings with the radiological images according to the PISAPED criteria. RESULTS: Only one of the 5 patients was diagnosed with PE. Two patients obtained pathological findings of the scintigraphy attributable to radiological alterations due to COVID-19 pneumonia, and the other two had normal pulmonary perfussion. CONCLUSION: Given the non-specific features of the clinical manifestations and D-dimer values in COVID-19, as well as their similarity to those of PE, the pulmonary perfusion scintigraphy plays a crucial role in the screening of PE in these patients due to its high sensitivity and lower irradiation compared to CT. Despite the limited number of patients, the results obtained have special relevance related to the absence of scientific publications on this group of patients within the context of COVID-19 pandemic exceptional situation.
