The integration of medical imaging technologies into diagnostic and therapeutic approaches can provide a preoperative insight into both anatomical (e.g. using computed tomography (CT), magnetic resonance (MR) imaging, or ultrasound (US)), as well as functional aspects (e.g. using single photon emission computed tomography (SPECT), positron emission tomography (PET), lymphoscintigraphy, or optical...
The role of the selective sentinel node biopsy (SNB) is increasing in relevance in breast cancer women with indication of neoadjuvant chemotherapy (NAC). The Radiosurgery Working Group of the SEMNIM is aware of the necessity of establishing the need for SNB before or after NAC, and also how to manage patients with axillary node-negative or node-positive. There is sufficient data to assess that the...
The case involves a 34-year-old who underwent surgical removal of a retroperitoneal paraganglioma adjacent to the left kidney lower pole, and visualized by CT and MRI.The 123I-MIBG scan was positive for this lesion and, in addition, another more caudal uptake, of smaller size and intensity, was observed at L5 level. It was not considered for removal, due to its lack of morphological definition.One...
Radio-guided surgery has been developed for application in those disease scheduled for surgical management, particularly in areas of complex anatomy. This is based on the use of pre-operative scintigraphic planar, tomographic and fused SPECT/CT images, and the possibility of 3D reconstruction for the subsequent intraoperative locating of active lesions using handheld devices (detection probes, gamma...
Definitive staging for cervical (CC) and endometrial cancer (EC) takes place once surgery is performed. The aim of this study was to evaluate the role of PET/CT in detecting lymphatic metastasis in patients with CC and EC using dual-time-point imaging (DPI), taking the histopathological results of sentinel lymph node (SLN) and lymphadenectomy as the reference.A prospective study was conducted on 17...
We analyze the case of a patient with left periorbital infiltrating basal cell carcinoma treated with surgical excision in October 2010. Surgery included orbital exenteration and reconstruction using skin graft and radiotherapy. In May 2013 a MR imaging showed a mass in the left orbital fossa, suggesting a recurrence in the graft. A basal cell carcinoma recurrence with perineural invasion was confirmed...
