Evaluation of patient effective dose from sentinel lymph node lymphoscintigraphy in breast cancer: A phantom study with SPECT/CT and ICRP-103 recommendations

EANM practice guidelines for lymphoscintigraphy and sentinel lymph node biopsy in melanoma

“…A low-dose CT scan with a field of view limited to avoid radiosensitive tissues can help to keep the effective dose to a minimum. For a low-dose CT scan for attenuation correction, an effective dose of 2.4 mSv has been reported [121]. The total exposure in such cases is the emission-generated dose plus the transmission-generated dose.…”

Role of SPECT/CT in Sentinel Lymph Node Detection in Patients With Breast Cancer

“…19,24 However, in a dedicated phantom study, Law et al evaluated the patient effective dose based on ICRP-103 recommendations. 30 Most of the effective dose received by the patient was due to the CT component, regardless of the surgical procedure (excision or not of the injected tissues) or the duration of the procedure (1-day or 2-day protocol). Although this was calculated for a specific CT device, it shows that the received irradiation is acceptable (total less than 3 mSv, which is close to the annual natural radiation dose).…”

The EANM practical guidelines for sentinel lymph node localisation in oral cavity squamous cell carcinoma

“…The different radiopharmaceuticals used for SLN imaging show minor differences in dosimetry. The local absorbed dose at the injection site with respect to the most common radiocolloids is less than 50 mGy/MBq [ 48 , 49 ]. In determining the effective dose, it should be considered that the radiolabelled colloid migrates minimally throughout the bloodstream or reticuloendothelial system (RES) or beyond the SLN and second-echelon lymph nodes.…”
