JAMMU, Aug 30: The newest technique to capture tumour motion is 4DCT Scan and this technique is being started by Shri Mata Vaishno Devi Narayana Superspeciality Hospital (SMVDNSH), Katra.
“The Patient was planned for treatment of lung tumor with 4DCT in which we used special sensors over the body to track the motion of tumor and subsequently CT pictures of different phases of respiration taken”, said Dr Vikas Roshan, Consultant Radiation Oncology at SMVDNSH.
“Then these CT pictures are separated as per different time frame gaps and finally we generated image in which all possible movements of patient tumor are captured”, he said, adding that in this patient they saved the adjacent organs like heart and esophagus and at the same time we delivered adequate radiation dose to the tumor.
He informed that the patient completed radiotherapy without any side effects like breathlessness and dysphagia. Patient is now on regular follow up and doing well, he added.
“We started this technique with patient of lung cancer in which radiotherapy delivery technique is modified as per the motion of lung tumor captured during CT scan. This new generation CT enables us to reduce the normal tissue irradiation surrounding Tumor which in turn leads to lesser toxicity” Dr Roshan stated.
