How accurate is CT scan for bladder cancer?

What can a CT scan of the bladder show?

A CT scan combines x-rays with computer technology to create three-dimensional (3-D) images. These scans can show stones in the urinary tract, as well as obstructions, infections, cysts, tumors, and traumatic injuries. Imaging for urinary stone disease can be done with low or ultra-low dose CT scans.

What is the best scan to detect bladder cancer?

It can also help show enlarged lymph nodes that might contain cancer, as well as other organs in the abdomen (belly) and pelvis.

How does ultrasound help with bladder cancer?

Ultrasound uses sound waves to create pictures of internal organs. It can be useful in determining the size of a bladder cancer and whether it has spread beyond the bladder to nearby organs or tissues. It can also be used to look at the kidneys. This is usually an easy test to have, and it uses no radiation.

Why is bladder cancer found?

Bladder cancer is often found because of signs or symptoms a person is having. Or it might be found because of lab tests a person gets for another reason.

Can a urine culture show cancer?

If you’re having urinary symptoms, this test may be done to see if an infection (rather than cancer) is the cause. Urinary tract infections and bladder cancers can cause the same symptoms. For a urine culture, a sample of urine is put into a dish in the lab to allow any bacteria that are present to grow. It can take time for the bacteria to grow, so it may take a few days to get the results of this test.

What type of tube is used for bladder cancer?

Is bladder cancer invasive or noninvasive?

This is very important in deciding treatment. If the cancer stays in the inner layer of cells without growing into the deeper layers, it’s called non-invasive. If the cancer grows into the deeper layers of the bladder, it’s called invasive. Invasive cancers are more likely to spread and are harder to treat.

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.
