The transport and intralymphatic deposition of interstitially injected radiocolloid of suitable physical properties are medi ated through physiological processes and provide the means for obtaining scintigraphic images of drainage lymph nodes relevant to the injection site. In a large series of patients with breast carcinoma, high correlation has been shown between the internal mammary lymphosc...

Erysipelas (cellulitis/lymphangitis) is a superficial cutaneous infection spread by the lymphatic system which may result in permanent injury to the lymphatic vessels. The study evaluated the lymphatic drainage in the lower limbs of 30 patients with at least two episodes of erysipelas by means of lymphoscintigraphy. Twenty-two (73%) were female and 8 (27%) were male with ages ranging from 26 to...

INTRODUCTION Lymphoscintigraphy is an important part of sentinel node mapping in breast cancer patients. Sometimes star shaped artefacts due to septal penetration can be problematic during imaging. In the current study, we evaluated the possibility of high energy (HE) collimators use for lymphoscintigraphy. PATIENTS AND METHODS Twenty patients with early breast carcinoma were included. Thirty...

UNLABELLED Lymphoscintigraphy allows functional assessment of lymphatic transport and depiction of regional lymph nodes, is fast and nontraumatic and has no known side effects. We retrospectively analyzed lymphoscintigraphic studies to determine their efficacy in the investigation of chyluria, chyloperitoneum and chylothorax. METHODS Twenty-one whole-body lymphoscintigrams using 99mTc-antimon...

introduction: in the current study we evaluated the incremental value of lateral pelvic lymphoscintigraphy imaging of endometrial or cervical cancer patients who underwent sentinel node mapping. methods: operable endometrial and cervical cancer patients without clinical or paraclinical evidence of lymph node involvement were included in the study. the day before surgery the patients were sent ...

Abstract Background Accurate sentinel lymph node (SLN) staging is essential for both prognosis and treatment in patients with breast cancer. However, the preoperative lymphoscintigraphy may fail to visualize SLN some patients. The purpose of this retrospective study was identify risk factors associated nonvisualization on lymphoscintigraphy. For single-center study, all data procedures from Mar...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

A. This guideline is written specifically for lymphoscintigraphy in patients with primary melanomas that originate in the skin. Staging of these tumors is based on tumor thickness (Breslow measurement) and level of skin invasion (Clark’s level), both of which are determined by the pathologist from a biopsy sample. Ample data correlate patient survival with Breslow and Clark measurements. In the...

introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

UNLABELLED Lymphoscintigraphy uses intradermal or interstitial injections of (99m)Tc-labeled tracers to produce images of focal lymph nodes. Because there is little or no anatomic information in the (99m)Tc images, a (57)Co flood source is sometimes used to provide transmission data along with the emission data. The anatomic shadow from the transmission scan generally improves interpretation an...
