you cant know it exactly. Even if theropods are closely related to birds, they also are relatives of the reptiles, in fact they are a special group of reptiles. And as many lizard and crocodiles have some sort of spikes or spines, it could be that T rex had them too. Many images show them with some sort of spines that go along his back. Also other dinosaurs had them. Sauropods for example are believed to have spikes and Carnotaurus who is actually a theropod is believed to have some too.
