Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain imaging methods in general terms, including safety, preparation and access to images, without interpreting individual scans or giving personal medical advice.

Techniques for creating images of the inside of the body for diagnosis and treatment, including X-ray radiography, mammography, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound and nuclear medicine imaging such as PET and SPECT, each with different uses, risks and preparations.

What it is for: Diagnosis, screening and guiding treatment.

It can be explain how imaging methods work; understand radiation dose and MRI safety in general terms; prepare for a scan; request copies of images and reports.

Distinguishing features

Non-invasive or minimally invasive

Several physical principles

Some use ionising radiation

Interpreted by specialists

What it looks like

Scanners, X-ray machines and ultrasound probes, producing grayscale or colour images.

How it is recognised

CT and MRI scanners

X-ray films and digital images

Endoscopy uses cameras inside the body

Principles.

How

How it works.

  1. How does this imaging method create images, in general terms? definition
  2. What is it typically used for? provenance

Compare

Comparison.

  1. How do CT, MRI and ultrasound differ in what they show? definition
  2. Who decides which test is appropriate? provenance
Safety Risks.

Safety rules apply.

Radiation

Dose.

Radiation

Radiation dose.

  1. How much radiation does this type of scan involve, compared with background radiation, according to health authorities? provenance
  2. What precautions apply in pregnancy? provenance

MRI

MRI safety.

MRI

MRI safety.

  1. Does the person have an implant, pacemaker or metal fragments that must be declared before MRI? boundary
  2. Who should they inform? action
Patient Preparation and records.

Patients can prepare.

Prepare

  2. How long does it take? provenance

Images

Copies and reports.

Images

Images and reports.

  1. How can a patient obtain copies of images and reports? provenance
  2. Is the user asking the agent to interpret their scan? boundary
Services Screening and access.

Access varies.

Screening

Programmes.

Screening

Screening.

  1. Which imaging screening programmes, such as breast screening, are offered here? provenance
  2. Who is eligible? provenance

Urgent

Urgent symptoms.

Urgent

Urgent symptoms.

  1. Does the person have urgent symptoms that need emergency care rather than a scheduled scan? boundary
  2. Should they call emergency services? action

What the second pass must settle

  • Should each modality be a separate entry?
  • How should dose information be linked?
  • How should screening programmes be linked?
