The aim of this study was to retrospectively determine the accuracy and feasibility of using 99mTc-dextran (DX) lymphoscintigraphy for the localization of sentinel lymph nodes (SLNs) in breast cancer patients. The relevant factors affecting lymphoscintigraphy were also investigated. In this study, 235 breast cancer patients underwent 99mTc-DX lymphoscintigraphic imaging and examination by a γ-p...

Introduction: Lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. Lymphoscintigraphy usually encompasses early or delayed static images. However, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. The aim of this study was ...

BACKGROUND The purpose of this study was to evaluate lymphatic drainage patterns of head and neck cutaneous melanoma observed on preoperative lymphoscintigraphy and sentinel lymph node biopsy (SLNB) and determine discordancy from clinically predicted lymphatic drainage patterns. METHODS We conducted a retrospective chart review of 114 patients with head and neck cutaneous melanomas evaluated ...

Lymphedema is a common clinical problem. Filariasis is the commonest cause of lymphedema in India and is a chronic debilitating disease. The purpose of this study is to highlight the role of lymphoscintigraphy in the evaluation of lymphedema. Our study population consisted of 418 patients diagnosed with filarial lymphedema of different clinical stages referred for lymphoscintigraphy of the limb...

Herein, we report a case of sentinel lymph node mapping in a uterine cervix cancer patient, referring to the nuclear medicine department of our institute. Lymphoscintigraphy images showed inappropriate intra-cervical injection of radiotracer. Blue dye technique was applied for sentinel lymph node mapping, using intra-cervical injection of methylene blue. Two blue/cold sentinel lymph nodes, with...

BACKGROUND The purpose of this report is to examine the viability and safety of preoperative lymphoscintigraphy and radio guided sentinel lymph node (SLN) biopsy for conjunctival melanoma, and to identify the best technique to perform this procedure. METHODS Three patients diagnosed with malignant melanoma of the conjunctiva underwent lymphoscintigraphy and SLN biopsy using a dual technique c...

OBJECTIVE To evaluate feasibility, SLN detection rate, and SLN location of lymphoscintigraphy in sentinel lymph node (SLN) biopsy for early cervical cancer. METHODS Ancillary analysis of data from the multicenter prospective SENTICOL study (January 2005-June 2007) of patients with early cervical cancer (FIGO stage IA with emboli to IB1) was conducted. Preoperative lymphoscintigraphy was perfo...

The purpose of this methods paper is to offer pediatricians and nuclear medicine physicians a diagnostic protocol for performing lymphoscintigraphy in newborns that may be useful for enhancing diagnosis and management of newborns with congenital lymphatic abnormalities. Indications for lymphoscintigraphy, choice of tracer, optimal dose, routes of administration, methods of data acquisition, tim...

We presented a 30 year-old woman presented with symmetrical swelling of the lower limbs since 5 years ago with sparing of the feet. She was highly suspicious of having lipoedema and was referred for lower limb lymphoscintigraphy to rule out possible lymphedema. Lymphoscintigraphy images showed asymmetrical injection sites and unusually high liver and spleen uptake. Inguinal nodes was not visual...
