Rationale

The integration updates the section with the most recent clinical practice guidelines for both peripheral artery disease (2024) and aortic disease (2022/2023). These guidelines represent the current gold standard for vascular imaging recommendations. I also expanded the PAD abbreviation on its first occurrence as per the instructions.

* **Advantages:** No ionizing radiation and excellent soft tissue contrast.
* **Techniques:** Time-of-flight (TOF), contrast-enhanced magnetic resonance angiography (MRA) (CE-MRA), and non-contrast MRA options for patients with renal insufficiency or contrast allergy. Vessel-wall imaging sequences provide enhanced characterization of vasculitis and arterial dissection.
* **Applications:**
  * Carotid and intracranial disease.
  * Aortic pathology, particularly in connective tissue disorders.disorders [@aha2022-b] [@aha2023].
  * Renal artery stenosis.
  * PeripheralLower arterialextremity peripheral artery disease (PAD) mapping when computed tomography angiography (CTA) is unsuitable.unsuitable [@svs2024-c].
* **Limitations:** Limited availability, higher cost, and contraindications including certain metallic implants, pacemakers, and claustrophobia.
* **Guidelines:** Recommended as alternative first-line imaging when CTA is contraindicated; modality choice should be guided by specific disease characteristics and patient factors. [@prince2016] [@aha2016] [@esc2017] [@esvs2018-esvs] [@esvs2019-aaa] [@aha2022-b] [@svs2024-c]
