PET SCAN RESULTS ACCURATE. Overall FDG-PET accuracy to diagnose lung cancer was 81.

Pet Scans In Cancer Cases

Uses of PET scan in lung cancer A PET scan can be widely used for diagnosing lung cancer to be a major contributor in the treatment of lung cancer.

How accurate are pet scans for lung cancer. Positron emission tomography PET scan. Used in combination of the biopsy it has proven to be a very useful tool in combating cancer. In previously published meta-analyses56FDG-PET was reported to be 90 to 94 accurate in the characterization of malignant or benign lung nodules with a sensitivity of 94 to 96 and specificity of 78 to 86.

MRI scans are most often used to look for possible spread of lung cancer to the brain or spinal cord. Like CT scans MRI scans show detailed images of soft tissues in the body. PET can determine possible cancer through an injection and a 30-45 min scan with a very acceptable percent of accuracy.

But MRI scans use radio waves and strong magnets instead of x-rays. The short answer is that a PET scan helps in the workup of an abnormality in the lung but can not definitely rule in or rule out a cancer. PET scans are performed along with a CT scan.

PET is generally more accurate than other imaging technologies such as. This combination scan is called a PETCT. In 113 indeterminate lesions 65 had lung cancer and the sensitivity and specificity were 89 and 40 respectively.

And was my CEA low because it didnt indicate cancer and isnt reliable for me or because the spots werent cancer. This is because the combined information from each scan provides a more complete understanding of the health problem. PET scan cancer detection accuracy - If There is cancer somewhere in the body this area will appear more active so that PET scans are often used to see if the cancer has spread to other parts of the body or to see how advanced the cancer is.

PET-CT scan for lung cancer PET-CT scans can help to show exactly where the cancer is in your lung and whether it has spread elsewhere in the body. Statistically speaking PETCT is far superior to CT in terms of diagnostic accuracy in solitary pulmonary nodule characterization. 1 The use of combined PETCT however provides more accurate information about presurgical lung cancer.

In the evaluation of metastatic spread to locoregional lymph nodes PET is significantly more accurate than CT so that invasive surgical staging may be omitted in many patients with negative mediastinal PET. The PET scan may be used in combination with a computed tomography CT scan to achieve a three-dimensional image that highlights the lungs health with accuracy. A PET scan is often ordered when there is uncertainty as to whether an abnormality found in the lungs is cancerous.

The test takes about 90 minutes. I dont want another PET scan and Ill always be suspicious that the spots showed up in the lung that I had the PE in. A PET-CT scan combines a CT scan and a PET scan.

His opinion was slightly different than the report the. Tissues with a higher metabolic rate higher energy usage such as lung cancer tumors absorb. The PET scan must be interpreted in the context of a patients complete medical history and the appearance of the abnormality in question on standard anatomic imaging such as the CT scan.

Preoperative positive likelihood ratio for FDG-PET diagnosis of lung cancer in this population was 15 compared with previously published values of 71. PETCT is 97 sensitive has an 85 specificity value a 92 negative predictive value NPV and a 93 positive predictive value PPV. Overall PETCT imaging provides 92 accuracy when diagnosing SPNs.

But PET scans perceived high accuracy in diagnosing metastatic non-small cell lung cancer NSCLC -- a published 94 sensitivity and 83 specificity in a 2001 JAMA meta-analysis -- may be vastly overstated and mask wide geographic variability according to more recent data. A lung PET scan is also used to stage lung cancer. PET scans have been shown to more accurately identify lymph node involvement with cancer compared to CT but both scans appear to have benefit.

PET scans are one of the latest tools used to detect and determine a cancers activity in the body. It gives detailed information about your cancer. It seems like too much of a concidence.

There are still insurance companies that will not acknowledge PET as a diagnostic tool. A second opinion at Dana Farber indicated that some of the spots on the PET Scan that were supposed to be mets were actually inflammation.
