What type of instruments will I be able to use when I become a radiologist.

Radiology is the medical specialty that uses medical imaging to diagnose and treat diseases within the human body.

The most common types of diagnostic radiology include:

• Computed tomography (CT), also known as a computerized axial tomography (CAT) scan, including CT angiography
• Fluoroscopy, including upper GI and barium enema
• Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
• Mammography
• Nuclear medicine, which includes such tests as a bone scan, thyroid scan, and thallium cardiac stress test
• Plain x-rays, which includes chest x-ray
• Positron emission tomography, also called PET imaging, PET scan, or PET-CT when it is combined with CT
• Ultrasound

I would also think that you may have to use a CT Machine and  PET machine depending on the types of issues.  If this is the field you would like to pursue, I wish you good luck in your endeavor.
