<br>Hi Benjamin,<br><br>Unfortunately the two measures that you indicated<br>are not sufficient for estimating maximum diameter,<br>nor volume of a tumor.<br><br><br>For further reading about clinically accepted <br>measures of tumor size, you want to look at:<br>
<br>RECIST Criteria:<br>(Response Evaluation Criteria in Solid Tumors):<br><a href="http://imaging.cancer.gov/clinicaltrials/imaging/">http://imaging.cancer.gov/clinicaltrials/imaging/</a><br><a href="http://en.wikipedia.org/wiki/Response_Evaluation_Criteria_in_Solid_Tumors">http://en.wikipedia.org/wiki/Response_Evaluation_Criteria_in_Solid_Tumors</a><br>
