The objective of this study was to study the characteristics of chyluria on radionuclide lymphoscintigraphy and evaluate the diagnostic value of radionuclide lymphoscintigraphy in chyluria. In this report radionuclide lymphoscintigraphy was performed in 41 cases of chyluria patients and the imaging results were retrospectively analyzed. Among 41 cases, 30 of them were caused by filariasis, 4 cases were secondary chyluria from abdomen surgery and 7 cases were caused by lymphangitis. Sixteen cases were proved as bilateral chyluria and 25 cases as unilateral chyluria by cystoscopy. The most common pattern of chyluria in radionuclide lymphoscintigraphy is that kidney or pelvis was imaged in the early phase of dynamic acquisition. In conclusion, radionuclide lymphoscintigraphy is a useful noninvasive method for detecting the origin site of chyluria, and for providing reliable information to perform safe operation.

cutaneous melanoma has often unpredictable lymphatic drainage patterns, especially at the level of the trunk, head and neck regions. Sentinel lymph node biopsy (SLNB) is an important prognostic tool that accurately assesses regional lymph node involvement and guides therapeutic decisions. Material and this prospective study involved 104 patients diagnosed with cutaneous melanoma who underwent SLNB using a radioactive tracer.

Background: Sentinel lymph node biopsy (SNB) using radioisotopes is a standard method for assessing axillary lymph node status in patients with breast cancer. Although preoperative lymphoscintigraphy can estimate the number of sentinel lymph nodes (SNs), multiple radioactive SNs are often identified, even when lymphoscintigraphy reveals only one SN. Importantly, metastases are not always observed in the most radioactive SN (hottest SN).

Background: Breast cancer is a global health problem, and sentinel lymph node biopsy (SLNB) is the standard procedure for early-stage breast cancer. Technetium-99 (TC-99), alone or combined with blue dye (BD) are conventional tracers for SLNB, but they have safety, availability, and cost limitations. Indocyanine green (ICG) is an alternative tracer that has been gaining acceptance among healthcare professionals.

Article Synopsis
- Lower extremity lymphedema is a frequent complication in patients treated for gynecological cancers, affecting up to 70% of them and currently lacking standardized treatment protocols.
- A case study details a 40-year-old woman who developed severe bilateral leg swelling and complications six years post-endometrial cancer treatment, ultimately leading to significant functional impairment.
- Following a combination of complex decongestive therapy and lymphaticovenous anastomosis, she experienced marked improvements, including substantial weight loss, reduced swelling, eliminated pain, and restored mobility.

Lymphoscintigraphy is a nuclear medicine procedure that uses a small quantity of radioactive particles for visualizing the lymphatic system. Traditionally, the radiotracer was injected subcutaneously, but the quality of lymphatic path imaging was scarce due to high background. Intradermal radiotracer injection is considered the modern-day intralymphatic injection.
