Head & Neck, ENT, Salivary and Dental Imaging
Evaluate neck spaces, mucosal disease, nodes, salivary glands, thyroid, temporal bone, sinonasal and dental pathology.
How to prepare for the current Final FRCR Part A
Build general-radiology breadth, then practise integrating clinical context, anatomy, multimodality findings, technique and management to select the single best answer.
Core concepts
Concept 1
Localise by fascial space and organ, then assess airway, skull base, perineural spread, nodal pattern and vascular relations.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Choose ultrasound, contrast CT, MRI, cone-beam or dental radiography, PET-CT and image-guided sampling for the exact question.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Recognise deep neck infection, airway compromise, vascular complication and malignant spread that alters surgery or radiotherapy.
Exam cue: Select the examination or intervention that changes management while accounting for contrast, radiation, access and urgency.
Concept 4
Apply normal and variant anatomy, modality technique, image quality and relevant imaging science to head & neck, ent, salivary and dental imaging.
Risk pitfalls and guardrails
Naming a neck mass without defining the space or organ of origin and its relationship to airway, vessels and skull base.
Guardrail: Do not anchor on one remembered sign; verify age, localisation, distribution, technique, alternatives and management consequence.
Do not choose a merely plausible SBA option before comparing every option with the full clinical and imaging context.
Guardrail: Re-read the command word and compare every option; the task is to select the best available answer, not the first plausible one.
Memory anchors
Neck-space localisation
Displaced fat, vessels, airway and glands reveal the compartment and narrow the differential.
Head and neck cancer spread
Assess deep spaces, cartilage or bone, skull base, perineural routes and nodal levels.
Salivary mass
Use gland and lobe, margins, signal, perineural disease and nodes; imaging cannot always determine histology.
Deep neck infection
Differentiate cellulitis or phlegmon from a drainable collection and assess airway, mediastinal and vascular complications.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A patient has a painless slowly growing parotid mass. MRI shows a well-circumscribed very T2-bright lesion with gradual enhancement in the superficial lobe. What is the most likely diagnosis?
An older male smoker has bilateral well-defined parotid-tail masses that are FDG avid and show early enhancement with washout. What is the most likely diagnosis?
Answer all questions to submit.
