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: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
Bilateral parotid and submandibular glands showed normal morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
An irregular, patchy soft tissue density shadow, approximately 7.5*4.8*10.8cm in size, is not clearly defined in the lower lobe of the left lung.
Lobulated margins are present, and calcifications are visible within.
FDG uptake is increased (SUVmax = 11.1).
There is bronchial obstruction in the anterior, medial, and lateral basal segments of the left lower lobe.
Multiple patchy shadows with increased FDG uptake are also present in the left lower lobe (SUVmax = 2.7).
Several small solid nodules are present in both lungs, the largest approximately 0.3cm in diameter, with no abnormal FDG uptake.
Multiple air-filled cavities are present in both lungs, along with scattered linear lesions, with no abnormal FDG uptake.
An air-filled sac-like shadow is seen at the right posterior margin of the upper trachea.
The left hilum, aortic window, and para-aortic arch lymph nodes are visualized, the largest approximately 1.9cm in short diameter, with increased FDG uptake (SUVmax = 11.2).
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with thickened walls, but localized FDG uptake was normal.
The pancreas was normal in shape, with no abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen was normal in shape and size, with multiple calcifications within it; FDG uptake was normal.
Both kidneys were normal in shape and size, with no abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters; FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was adequately distended, with slight thickening of the gastric antrum wall and increased FDG uptake; SUVmax = 3.5.
Intestinal distension was unsatisfactory, with no local masses observed.
Linear calcifications were observed in the sigmoid colon and rectal walls, with no abnormal FDG uptake.
The prostate was full, with patchy dense shadows inside, and no abnormally increased FDG uptake was observed.
Bladder distension was poor, with no obvious positive stones observed.
Multiple enlarged lymph nodes were found in the retroperitoneum and right pelvic wall, the largest with a short diameter of approximately 3.2 cm, showing increased FDG uptake (SUVmax = 11.1).
The iliopsoas muscle of the right pelvic wall was involved.
Overall bone density was decreased, the spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, multiple intervertebral disc bulges, pneumoconiosis and degeneration of the L4/5 intervertebral disc, and increased density and roughness at the relative margins of the L5/S1 vertebral bodies.
FDG uptake of the entire skeleton was normal.
Increased FDG uptake was observed around the left ischial tuberosity (SUVmax = 3.0).
A subcutaneous calcified nodule was found in the occipital region, approximately 0.7 cm in diameter.

Impression

1. a. Irregular mass in the left lower lobe with increased FDG metabolism, suggestive of lung cancer with obstructive inflammation; please correlate with clinicopathology. b. Multiple metastatic tumors in the left hilum, mediastinum, retroperitoneum, and right pelvic wall.

2. Bilateral emphysema, bilateral chronic inflammatory micronodules. Scattered post-inflammatory lesions in both lungs. Tracheal diverticulum. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Splenic calcification. Benign prostatic hyperplasia with calcification.

4. Schistosomiasis intestinal manifestations, chronic inflammatory changes in the gastric antrum.

5. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges, L4/5 intervertebral disc pneumoconiosis, L5/S1 vertebral endplate inflammation. Inflammation around the left ischial tuberosity.

6. Senile brain, deep lacunar infarcts. Subcutaneous calcified nodules in the occipital region.

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.
