Consider the following facts:

1. Magnetic Resonance Imaging (MRI) is a less effective way of picturing the interiors of the body than an X-ray.
2. It is an application of nuclear medicine, since it uses nuclear magnetic resonance to create images of nuclei within the body.
3. In this technique, a patient is actually made to lie within a large magnet before his interior organs can be pictured.

Which of the above is/are true?

Magnetic Resonance Imaging (MRI), Nuclear Magnetic Resonance Imaging (NMRI), or Magnetic Resonance Tomography (MRT) is a medical imaging technique used in radiology to visualise internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. MRI can create more detailed images of the human body than are possible with X-rays. An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetisation of some atomic nuclei in the body, and radio frequency magnetic fields are applied to systematically alter the alignment of this magnetisation.
