Positron emission tomography (PET)

Bowel cancer: Do PET scans improve treatment for recurrent tumors?

If there is good reason to suspect bowel cancer recurrence, positron emission tomography (PET) or a combination of PET and computed tomography (PET/CT) can detect new tumor growth better than conventional methods. Yet it remains unclear whether this improves treatment, giving those affected by bowel cancer noticeable benefits. more...

Brain tumors: What benefit does a PET scan have in recurrence of high-grade gliomas?

Whether positron emission tomography (PET) for detecting recurrence improves the treatment of people who have high-grade glioma, has not been studied in suitable trials. It also remains unclear how accurately recurrence can be determined using PET. more...

Head and neck tumors: Is a PET examination more exact than routine examinations, and does it lead to better treatment?

It is not yet clear whether cancer in the head and neck region can be diagnosed more precisely by using positron emission tomography (PET) or PET / computed tomography (PET/CT), and whether recurrences can be more reliably detected than is possible with standard examinations. It has also not been possible to estimate what kind of an influence it has on the success of treatment. more...

Skin cancer: What benefit does positron emission tomography have for treating malignant melanoma?

It is not clear whether positron emission tomography (PET) or PET / computed tomography (PET/CT) improves the treatment of people who have malignant melanoma. It is also not known how exact these procedures are in determining the size, location and spread of a melanoma. more...

Ovarian cancer: Can a PET scan improve treatment?

Positron emission tomography (PET) alone or PET in combination with computed tomography (PET/CT) can detect recurrence of ovarian cancer more reliably than conventional tests and examinations. It is unclear, however, whether PET and PET/CT do indeed lead to better treatment of women with ovarian cancer. more...
