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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were normal, and the bilateral parapharyngeal spaces were clear with normal FDG uptake.
The palatine tonsils showed physiological uptake.
A soft tissue nodule, approximately 0.8 cm in long diameter, was observed in the left parotid gland, with increased FDG metabolism (SUVmax = 5.9).
No abnormal density shadows were seen in the right parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly heterogeneous density; FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Increased translucency was observed in both lungs, accompanied by multiple air-filled cavities.
An irregular mass, approximately 5.4 4.2 cm in size, with lobulated and spiculated margins, was seen in the right middle lobe; FDG metabolism was increased (SUVmax = 19.6).
A few punctate foci, calcifications, and linear foci were also observed in both lungs; FDG metabolism was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Several small lymph nodes were observed in the bilateral pulmonary hila, pretracheal space, para-aortic arch, main pulmonary window, and below the tracheal carina, the largest being approximately 0.5 cm in short diameter.
FDG metabolism was increased, with SUVmax = 3.6.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses, and FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake 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, with slightly thickened walls and irregular dense shadows filling the lumen.
FDG metabolism was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
A cystic lesion was seen in the right kidney, approximately 5.7 cm in long diameter, with absent FDG uptake.
Punctate dense shadows were also seen in the right kidney.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter.
FDG uptake was not significantly abnormal.
A low-density shadow, partially containing fat density, was seen in the left adrenal gland, approximately 1.3 cm in long diameter.
FDG metabolism was normal.
No obvious abnormalities were seen on the right adrenal gland.
Stomach distension was poor, with slight thickening of the walls in parts of the gastric body and antrum.
FDG uptake was slightly increased, SUVmax=2.3.
Intestinal distension was unsatisfactory, with increased FDG metabolism in parts of the intestine (SUVmax=4.5); FDG metabolism at the anus was also increased (SUVmax=5.9).
The prostate is normal in size and shape, with uniform density, and no abnormal FDG metabolism was observed.
The bladder is generally full, and no obvious positive stones were seen within it.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The left inguinal canal is dilated, and FDG metabolism is normal.
Several lymph nodes are seen in both inguinal regions, with a short diameter of approximately 0.5 cm, and FDG metabolism is normal.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, calcification of some anterior longitudinal ligament, nuchal ligament, and supraspinous ligament, and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Right middle lobe lung mass, increased FDG metabolism, suggestive of peripheral lung cancer; please correlate with clinicopathology. b. Scattered chronic inflammation and old lesions in both lungs. Bilateral emphysema. Highly likely reactive hyperplasia of hilar and mediastinal lymph nodes; follow-up examination recommended. Calcification of some arterial walls (including coronary arteries).

2. Chronic cholecystitis; gallstones. Right renal cyst. Right renal calculus. Left adrenal medullary lipoma; CT follow-up recommended.

3. Slight thickening of the walls of part of the gastric body and antrum, mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in part of the intestines, suggestive of inflammatory or physiological uptake. Hemorrhoids. Follow-up gastroscopy and colonoscopy are recommended for all of the above.

4. Enlargement of the left inguinal canal; please correlate with clinical findings. Reactive hyperplasia of bilateral inguinal lymph nodes.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

6. A few ischemic lesions in the deep bilateral brain regions; age-related brain abnormalities. A left parotid gland lymphoma is highly probable; ultrasound follow-up 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.
