What is the blue light in a cystoscopy?

Fluorescence cystoscopy (also known as blue light cystoscopy) may be done along with routine cystoscopy. For this exam, a light-activated drug is put into the bladder during cystoscopy. It’s taken up by cancer cells. When the doctor then shines a blue light through the cystoscope, any cells containing the drug will glow (fluoresce). This can help the doctor see abnormal areas that might have been missed by the white light normally used.

Imaging Techniques To Detect Bladder Cancer

Imaging techniques, which include ultrasound, computed tomography (or CT) scanning, magnetic resonance imaging (or MRI) and x-ray approaches, provide an important means of assessing the urinary tract, including the kidneys, and play an important role in the detection, diagnosis, and monitoring of bladder cancer.


Detecting bladder cancer with ultrasound

An ultrasound (which may also be referred to as a sonogram) uses high frequency sound waves to produce images of internal organs. Echoes, which are created as sound waves bounce off organs and tissues, produce computer images that provide information on the structure and movement of organs and the blood flow through vessels.

How do ultrasounds help detect and monitor bladder cancer?

An ultrasound of the urinary tract can help assess the size of a bladder tumour and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumours, however, it cannot determine if a tumour is cancerous. Ultrasound can also be used to guide a biopsy needle to sample a suspected cancer.

Detecting bladder cancer with CT scans

A CT scan uses x-rays to obtain cross-sectional images of the body. Compared to a general x-ray test, which directs a broad x-ray beam from a single angle, the CT scan uses a number of thin beams to produce a series of images from different angles.


Other imaging approaches to detect or monitor bladder cancer

An MRI scan uses radio waves and magnets to produce more detailed pictures of soft tissues. MRI scans can show whether bladder cancer has spread to other tissues or to the lymph nodes. To improve the quality of the images it’s sometimes necessary to administer an intravenous dye.

Why do you need a bladder CT scan?

Some reasons to request a bladder CT scan can include incontinence, bladder masses, or signs of blockages. This test can also be requested if a doctor suspects the presence of stones in the bladder.

If a patient is already hospitalized for an existing medical problem, the test can be offered as an inpatient service, in which case people can transfer to the radiology department for the test and return to their beds when they are finished.

Is a bladder CT scan safe?

Risks associated with a bladder CT scan are low. Patients are exposed to some radiation, but it is kept as low as possible and the benefit of catching a problem outweighs the risk. Pregnant women may be advised to wait for testing if at all possible because of the increased risks for the developing fetuses. Some people experience allergic reactions to contrast agents, and it is important to discuss past allergy and medical history with a medical provider before starting the test. The technician may decide to use a different contrast agent or consider a bladder CT without contrast if this appears necessary.
