- Primary Outcome Measures
Name Time Method <p>The primary outcome is to determine the feasiblity and applicability of the MRL<br /><br>protocol by evaluating the images of the upper extremity in patients with<br /><br>secondary lymphedema and healthy subjects. MRL images and 3D MIPs will be<br /><br>evaluated by an experienced radiologist and plastic surgeon and scored on the<br /><br>following points: qualitative and quantitative visibility of veins and lymph<br /><br>vessels, location, depth, (abnormal) pattern, diameter, and overall image<br /><br>quality on a scale of 10.<br /><br>Moreover, differences in the lymphatic system between the lymphedema patients<br /><br>and healthy volunteers will be assessed. </p><br>
- Secondary Outcome Measures
Name Time Method <p>The images and 3D MIPs will be compared with clinical staging according to the<br /><br>International Society of Lymphology (ISL) classification and Indocyanine green<br /><br>(ICG) lymphography. Clinical classification and ICG Lymphography is performed<br /><br>as standard care at the outpatient-clinic to evaluate lymphedema and as workup<br /><br>for surgical treatment. The dermal backflow stage, as described by, is used in<br /><br>the staging of lymphedema. </p><br>
