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.
No thickening of the paranasal sinus mucosa; intact sinus walls.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the left parotid gland and bilateral submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
A soft tissue density nodule is seen in the deep lobe of the right parotid gland, with a cross-sectional size of approximately 1.8*1.2cm, showing increased FDG metabolism (SUVmax=14.5).
A lobulated nodule is seen in the upper lingular segment of the left upper lobe, closely adhering to the oblique fissure pleura, with spiculated margins and indistinct borders, measuring approximately 2.2*1.6cm, showing increased FDG metabolism (SUVmax=6.0).
Multiple solid small nodules are observed in both lungs, with regular shape, clear borders, and a long diameter of approximately 0.2-0.5cm; FDG uptake is normal.
A few linear and flocculent density shadows are also seen in both lungs; FDG metabolism is normal.
There is no pleural effusion or pneumothorax bilaterally.
Lymph nodes were observed in the bilateral hilar and mediastinal tracheal and posterior vena cava windows, and in the main pulmonary artery window.
The largest node had a short diameter of approximately 1.0 cm, with some showing increased FDG metabolism and an SUVmax of 3.5.
The heart was slightly enlarged.
Some arterial walls showed calcification (including the coronary arteries).
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and slightly heterogeneous liver parenchyma density.
A small, low-density nodule with smooth margins and a long diameter of approximately 0.4 cm was seen in the left lobe of the liver on plain CT scan, with absent FDG metabolism.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall.
The gallbladder lumen showed slightly heterogeneous density, and localized FDG metabolism was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormalities in FDG metabolism.
Spleen morphology, size, density, and FDG metabolism were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG metabolism was normal.
No obvious abnormalities were observed in the bilateral adrenal glands.
The esophagus was not dilated, and no obvious thickening or mass was observed in the esophageal wall; FDG metabolism was not increased.
The stomach was generally full, with no obvious thickening of the stomach wall; FDG metabolism was normal.
Intestinal fullness was poor; FDG metabolism was increased in parts of the colon and rectum, SUVmax=4.0.
The prostate was full in shape, with high-density shadows in the parenchyma; FDG metabolism was normal.
The bladder was poorly full, with no obvious positive stones observed.
Fluid density shadows were observed in both scrotums; FDG metabolism was absent.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Decreased bone density was observed throughout the body; the spinal alignment was normal; calcification of the nuchal ligament was observed; and osteophyte formation was present at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges were observed, with normal FDG metabolism.
Increased FDG metabolism was observed around the right shoulder joint, with SUVmax = 3.3.

Impression

1. a. A mass in the left upper lobe, lingular segment, closely adhering to the oblique fissure pleura, with increased FDG metabolism, highly suggestive of peripheral lung cancer; please correlate with clinicopathology. b. Multiple small, solid, chronic inflammatory nodules in both lungs; please follow up with CT scans. A few post-inflammatory lesions in both lungs. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes; please follow up. c. Slightly enlarged cardiac silhouette, with partial arteriosclerosis (including coronary arteries); specialist follow-up is recommended.

2. A nodule with increased FDG metabolism in the deep lobe of the right parotid gland, highly suggestive of a mixed parotid tumor; specialist follow-up is recommended.

3. Hepatic parenchyma with uneven density, small cyst in the left lobe of the liver, and possible gallbladder polyps; ultrasound follow-up is recommended for all of the above. Benign prostatic hyperplasia with calcification. Bilateral hydrocele.

4. Increased FDG metabolism in parts of the colon and rectum, possibly due to physiological uptake or chronic inflammation; please follow up with endoscopy.

5. Osteoporosis, degenerative changes in the spine. L4/5 and L5/S1 disc bulges. Right-sided frozen shoulder.

6. Age-related brain changes, deep lacunar infarcts; MRI is recommended.

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.
