Whole-body 18F-FDG PET/CT scan in a patient with Lung Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in the bilateral ethmoid sinuses; intact sinus walls; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
Poor pneumatization of the bilateral mastoid processes.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
A soft tissue density mass is seen in the left upper hilum near the opening of the lingular segment of the left upper lobe bronchus.
The mass has indistinct borders, a cross-sectional size of approximately 4.0*2.7cm, and shows increased FDG metabolism (SUVmax = 19.3).
Spotty, patchy, and consolidation shadows are seen around the lesion.
Scattered solid micronodules and calcifications are present in both lungs, with regular shapes and clear borders, a long diameter of approximately 0.2-0.4cm, and FDG uptake is normal.
A few linear and flocculent density shadows are also seen in both lungs, with normal FDG metabolism.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax.
Left hilar lymph nodes were observed, the largest measuring approximately 1.8*1.0cm, with increased FDG metabolism and an SUVmax of 23.1.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan.
FDG metabolism was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no localized FDG metabolism abnormalities.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormalities in FDG metabolism.
The spleen showed no abnormalities in shape, size, density, or FDG metabolism.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
Punctate dense shadows are seen in the left renal calyx.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG metabolism is normal.
No obvious abnormalities are seen on bilateral adrenal gland contrast.
The esophagus is not dilated, and no obvious thickening or mass is seen in the esophageal wall.
FDG metabolism is not increased.
The stomach is generally full, with no obvious thickening of the stomach wall, and FDG metabolism is normal.
The intestines are poorly full, with no obvious thickening or mass in the intestinal wall, and FDG metabolism is physiological.
The prostate is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma, and FDG metabolism is normal.
The bladder is poorly full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious effusion is seen in the abdomen or pelvic cavity.
The spinal alignment is normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
There are L4/5 and L5/S1 intervertebral disc bulges, with no abnormalities observed in FDG metabolism.
A Schmorl's node is visible at the superior margin of the S1 vertebral body, with no abnormalities observed in FDG metabolism.

Impression

1. a. A mass near the bronchial opening in the lingular segment of the left upper lobe at the left upper hilum, with elevated FDG metabolism, consistent with lung cancer, and left hilar lymph node metastasis. A few atelectasis or inflammations in the lingular segment of the left upper lobe. b. Scattered chronic inflammatory micronodules (solid and calcified) in both lungs; please follow up with CT scans. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis (including coronary arteries).

2. Left kidney stone.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Schmorl's nodes at the upper margin of the S1 vertebral body.

4. Age-related brain changes; deep lacunar infarcts in the brain; MRI is recommended. A few ethmoid sinuses bilaterally. Poor pneumatization of the mastoid process bilaterally.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
