UHS PGET Radiology: Neuroradiology & Chest Radiology MCQs With Explanations

Practice MCQs on neuroradiology and chest radiology for UHS PGET Radiology prep, with one-line explanations. Two of the bank's largest specialty subjects, covered in one page.

UHS PGET Radiology has two papers: Paper I (MBBS basic medical sciences) and Paper II (the specialty paper). This page gives you sample Neuroradiology and Chest Radiology MCQs with short explanations -- two of the largest specialty subjects in the bank -- so you can see the level of detail expected before you commit to a full prep plan.

Why Neuroradiology and Chest Radiology First

Across the full PGET Radiology question set, Neuroradiology and Chest Radiology are two of the heaviest specialty subjects -- together they carry more weight than most other single specialty topics in the bank. Candidates who are short on time get the most return from mastering these two before moving to lower-yield subjects like breast or nuclear medicine imaging.

Sample Neuroradiology MCQs

1. Which MRI sequence is most sensitive for detecting an acute ischemic stroke within the first few hours of onset?

A) T1-weighted imaging
B) T2-weighted imaging
C) Diffusion-weighted imaging (DWI) ✅
D) Gradient echo (GRE)

DWI detects the restricted diffusion of cytotoxic edema within minutes of ischemic onset, well before T1/T2 changes become visible -- it is the standard first-line sequence for suspected acute stroke.

2. On a non-contrast CT brain, acute intracranial hemorrhage typically appears as:

A) Hypodense
B) Isodense
C) Hyperdense ✅
D) Signal void

Fresh hemoglobin-rich clot attenuates X-rays more than brain tissue, so acute hemorrhage is bright (hyperdense) on CT. It becomes progressively less dense as the clot ages over 1-2 weeks.

3. In an HIV-positive patient from an endemic region, a solitary ring-enhancing brain lesion on contrast CT is most classically caused by:

A) Glioblastoma
B) Toxoplasmosis ✅
C) Tuberculoma
D) Metastasis

Toxoplasmosis is the classic cause of ring-enhancing lesions in HIV/AIDS patients in endemic settings, often with a target/eccentric-nodule sign and basal ganglia predilection.

Sample Chest Radiology MCQs

4. Loss of the right heart border on a chest X-ray localises pathology to which lobe?

A) Right upper lobe
B) Right middle lobe ✅
C) Right lower lobe
D) Lingula

The silhouette sign: the right middle lobe sits adjacent to the right heart border, so consolidation there effaces it. Lingular pathology instead effaces the left heart border.

5. Kerley B lines on a chest X-ray are a classic sign of:

A) Pneumothorax
B) Interstitial pulmonary edema ✅
C) Lobar pneumonia
D) Pleural effusion

Kerley B lines are short horizontal lines at the lung periphery caused by fluid in interlobular septa, most commonly from cardiogenic pulmonary edema.

6. An air bronchogram on chest imaging indicates pathology in which compartment?

A) Pleural space
B) Airspace (alveolar) ✅
C) Mediastinum
D) Chest wall

An air bronchogram is air-filled bronchi made visible against surrounding fluid- or pus-filled alveoli -- it localises disease to the airspace, as in consolidation, and argues against a purely pleural process.

How to Use These Questions

Attempt each question before reading the explanation, and note which ones you got right for the wrong reason -- that is where your real gaps are. In the full QBank, Neuroradiology and Chest Radiology are tagged separately so you can drill each as a dedicated block, then move to Timed Mode once your subject-wise accuracy is consistently above 70%.
